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

Like I said. Those extra 4 pins in the R system may eventually make an expensive new body not perform optimally with an EF lens. I have read from members here that the AF 100-500 AF acquisition is faster than the EF 100-400II on an ML body. If acquisition is faster then tracking is better and IS/IBIS responds faster. Does this make an EF lens obsolete. Not by a long shot but may be very noticeable one day.

I do know that AF is insane with my R7 compared to my R5. Not that the R5 was bad. The tech just keeps improving.

I have only had my R5 for a couple of months and so far my only RF lens is the 24-105 that I bought with the camera.  I have no doubt that AF is probably much better with an RF 100-500, but when I went to Bosque Del Apache with the R5 and my Sigma EF 150-600 C, I was more than happy with the AF performance.  (I did make camera AF and lens corrections per Duade Paton's suggestions).   At no point did I feel like I was having issues with AF that made me feel compelled to run out and buy a RF 100-500.  Again, that's not to say the RF lens wouldn't be better - I'm sure it would be - but what I have is serving my needs just fine and I came away with some amazing images.

I will acquire more RF lenses in the future, I'm sure, but I don't feel like I'm unable to get great images with the many EF lenses I currently have.
