I have difficulty to understand somebody going for a very small M camera and then use adapters to use typicaly oversized EOS lenses. Doesn’t hide very limited lens selection. But hey, that is my view.

Add detachable viewfinder only for top body and there is a system that is very limited. Only Canon can sell that. ;-) Mostly sold by brand name and price (low). Short term succesful strategy to take away market share from competitors, no doubt. Longterm less so.

Tele lenses will be similr in size, with or without adapter. So your view is kinda skewed. The detachable view finder depends on the form factor. M6 yes, M5/M50 no.
