These commands exist for the last year.  I'm not sure how reasonable
it is to rename them now, they are probably used in umpteen places
outside Emacs already.  Maybe if we leave behind an alias.

And what if someone teaches these commands to downgrade as well, at
some future time?

Does anyone else have an opinion?  Lars, Stefan, Philip?
