Totally, this is part of the problem I'm trying to solve. I wrote a little about these "call to action links" that you're describing in the proposal.[0] The tl;dr is that I think it would be easier to hold the line that "links should look like links" if we supported the legitimate use cases for navigating with buttons.

I would love more feedback from the accessibility engineering community so please look up my email or comment on the proposal if you think I've missed something.
