Or maybe I just scrolled to the bottom after reading the whole text
straight through and want to jump to the context of the footnote
I'm now reading. (The footnote and its context could be in the same
document, too, y'know.)

I think you're missing the point here. 'rev' doesn't say anything more
about the linked document than 'rel' does. It's just a way of expressing
inverse relationships without having to pull out thesauri and latin
prefixes and excessive hyphens.

The user agent doesn't need to do anything to make the markup useful:
if you look at XFN, for example, UAs didn't support any of it, but
authors still used the markup as hooks to for styling.

I don't think I need to say anything about how ridiculous a counter-
suggestion that is.
