I think the answer is YES, EF lenses will continue to work if not explicitly supported,

however there is no guarantee that there won't be future camera features which will only work with RF lenses because of certain EF lens electromechanical performance limitations. And perhaps Canon will contrive to make that happen

That much was true from the very beginning. There are already features that only work with RF lenses. That's not a matter of "contrivance," that's a matter of progress.

yes but Canon might design some features that only work with RF lenses - could be some form of advanced in-camera focus stacking etc - ie features deliberately designed to add value to RF lens ownership but offer nothing to EF lens users.

I would be OK with this - it's reasonable for a new feature to require both a new spec body and a new spec lens. There are already minor examples of this, like the distance scale in the viewfinder which anybody who has an exclusively EF lens collection will never have seen. […]

Another example is the focus breathing correction introduced with the R6II. I’m not sure if the needed data is delivered by the lens, like all other corrections for RF, or stored in the body firmware, like we had with EF.
