Third party lens makers will move from the EF mount to the RF mount. They don't care what happens to their EF lenses other than if the sales numbers drop, so do the lenses.
If too many EF users just buy an RF body and an adapter for their EF lenses, Canon will have to look at forcing people to buy RF lenses.
When they made the EF mount they shortened the registration distance just enough to make it virtually impossible to mount FD lenses. Sure, they made an adapter with an optical element to make it possible, but it was a quality killer and they stopped making it after a few years anyway. If one wanted to use FD lenses, one had to have an FD camera, which Canon also stopped supporting through their service centers.
Meanwhile, Canon was laughing all the way to the bank.
I really don't see how keeping support for EF lenses on RF cameras is going to be in Canon's best self interest in the long haul. Those old lenses with an adapter can do nothing but erode new RF lens sales.
History tells us what Canon will be looking at doing.
