Just a thought, could Canon slowly phase out the compatibility of EF lenses on future RF bodies….to increase new sales revenue from RF lenses?

They could, because the EF-RF adapter is just a dumb adapter - all the protocol conversion is done by the camera, which knows how to communicate with an EF lens. It would clearly be possible to remove this feature. It wouldn't even have to be a future body - it could be done with a firmware update.

But whether they would is a different question. I think it would be the final straw for many people, who are already frustrated that Sigma, Tamron and others are locked out by Canon's closed system.

Sigma, Tamron and others are not locked out from Canon. They work flawlessly or R cameras via adapter.

You know perfectly well what I mean, no need to be one of those internet ####s. Sigma and Tamron are locked out of the RF mount.

Canon did their best to lock them out of EF mount, and FD mount before that, too.  Sigma only became fully usable with EF mount after their dock made their lenses user updatable.  But Canon have a lot more to lose than they have to gain by making RF mount cameras incompatible with their own EF lenses.

And Sigma will eventually find a way, but they need to be right first time. I use 30 year old Canon EF lenses on RF and EF-M mounts but I'd think twice about using a 15 year old Sigma.
