electronic shutter

Hello, I have been shooting outdoors in natural sunlight this morning with the electronic shutter with the EOS R7 + EF-S 18-135 nano USM... and I notice although it is very subtle, but there are some kind of horizontal stripes or bands in clear areas of the blue sky like the photo attached here...

Hi, what do you think of an open petition towards Canon to add camera features to R5/6 like the pre release capture function, and variable burst shooting speeds for the silent mode/electronic shutter, and last but not lease add the function to simply play optional click sounds when taking photos...
