For Canon it's really necessary. Canon make no money on S/H gear sales so instead they release a series of slightly / incrementally better lenses over time and slightly lower the RRP for each model. The net effect is to plunder the used values of the previous lens and encourage people to buy the newest version.
If you look at the ef 70-200mm f2.8 LIS mk II's S/H value compared to the very slightly improved mk III (mostly flourine coatings to the front element). The mkIII sells for a lot more than the mkII even though they are essentially the same lens. The RF versions will go the same way. A suprisingly fast refresh rate, with each new model crashing the used value of the previous generation.
Gone are the days of mint lens investment, where you Canon lenses would actually aquire value as time passed. When i bought my (then new) EF 85mm f1.2 II L for £899 (from an old fashioned local camera shop). Over the next 8 years of ownership, the new price jumped to £1899 and my lens was then worth £1200 on the used market.
These days a top tier RF lens like a RF 85mm f1.2 L initally has a very high price and limited availability. Then it drops a bit but stays stable as their supply meets demand...then after a few more years, Canon will release a slightly better mkII and the used value of the previous version will drop like a brick. Your lens is now worth half of what you paid for it. Then a few years later Canon drop a mkIII version, with very marginal improvement and violla...your mk I lens is now worth even less.
So my advice is buy a lens, use it and consider it a long term creative investment and don't get too hung up on getting the latest mkII or mk III. This is why I'm still rocking a LOT of top tier EF L lenses.

It is always great to think about 200mm to cover distances when it comes to underwater work ....The 24-105Z makes me think a 70-200Z is in the works.
The lensrentals tear down showed that it was much better designed and built than its competitors, but some people can’t be swayed by reality.
Apart from sealing, there are other reasons for preferring and internal zoom, like gimbal or underwater works. But you already known that

Not just holding top tier EF L lenses but investing in top tier 3rd party lenses like Zeiss Milvus. There are bargains on the market for some of the great among them and nothing beats the richness of their colors.
Select the RF where you get unmatched IQ size ratio, i.e. the RF 28 Pancake.

The Panasonic one doesn't do 1.4x magnification and lacks IS, so it sacrifices a lot of features to get down to that size. I bet it has horrible focus breathing as well.

Canon RF 28-70mm f/2 USM L Review - OpticalLimits
Review by Klaus Schroiff, published April 2022 Introduction The Canon RF 28-70mm f/2 USM L was one of the first lenses for the RF-mount cameras. You may also say that it was nothing short but a STATEMENT because it’s the world’s first full-format standard zoom lens with a constant max aperture...

If this is not good enough performance for an f/2 constant aperture zoom, I don't know what is. Maybe you tested a lesser copy.
I am sure they can do better still but beyond a certain point, it's just not relevant anymore, especially in the field.
Patent does exist for a 24-70/2 with a similar size, so I was referring to that. Rumour does not state it will have the same exact range.

I've seem people state that the IQ loss occurs at distances less than 5m, assuming that's the case, I suspect that the test charts Optical Limits uses are used at a greater distance.Canon RF 28-70mm f/2 USM L Review - OpticalLimits

I have very little personal experience with the RF28-70L, I rented it for a week and decided it was too heavy to be enjoyable to use, for me.

As much as I love nerding on about those extremely expensive lenses, I'd much rather like to see a mark2 version of the 24-105 F4.
In times of amazing noise reduction software and good high iso performance in cameras, I actually prefer the f4 versions over most f2.8 because of the smaller size and weight.
But the 24-105 really performs below par for an L lens.

I own the lens, and do not think the auto focus is lazy what ever that means?
Shooting on the R5 and R3. The lens is wonderfully heavy, due to all that glasss and I love the lens. Then again, I hand hold my 600 f/4

It will come eventually....once Canon has bled the 28-70/f2.0 version dry. Canon did this with the original 28-70mm f2.8 > 24-70mm f2.8.
These days Canon are dropping a few MkII's and mk III's into the line up before they drop the big upgrade. Why sell one lens when you can shift three over time.

I suppose it's relative. I’d say the 28-70/2 focuses reasonably quickly, but it’s perhaps two ‘notches’ slower than lenses like the RF 70-200/2.8 or RF 24-105/2.8, which are among the fastest-focusing lenses. Lenses like the RF 24-105/4, RF 100/2.8 and RF 100-500 are in between.
I’d put the AF speed of the 28-70/2 on par with STM lenses like the 24/1.8 and 28/2.8. It’s not the EF 85/1.2L, but it doesn’t have blazing fast AF like some other lenses. I can tell the 28-70/2 is focusing, there is a noticeable lag between when I press AF-ON and when focus locks. By comparison, the 24-105/2.8 seems to instantly snap to focus lock.
Those are my impressions not formal testing, but they’re based on me mounting all of the above-mentioned lenses (except the EF 85/1.2L II that I sold years ago) on my R3 one right after another and focusing around a room with each of them.
The 28-70/2 uses Ring USM, suggesting the focusing group is heavy. If Canon redesigns it with two smaller focus groups with dual Nano USM, that would speed up focus considerably.
