Better to have more options than no options. I would skip those personally, too, but others can decide if the difference is worth it for them (especially on 24MP). Some want 2.8 zooms (especially 24-70) and it is not worthwhile for Leica to develop these, same with cheaper 1.8 primes.
I'm expecting the 24-70 2.8 II to be rebranded as well at some point, and it looks quite decent.
While the AF can't bother me either (had the 24-90/2.8-4, worked fine in single-AF), there are many other body features that annoy the hell out of me (changing some settings are just slow and more tedious next to Canon).
Looking forward to the R6 III, should be a lot closer to an "all-round midrange" camera, but they will find ways to cripple it.
(It could remain dual SD slots limiting RAW recording, C-Log 3 only, still no level or histogram during recording, switching modes has always been inferior to the R5 line, lesser LCD, jada, jada).
