I thought the point was to not break existing _code_. Making people
change what they physically type isn't only acceptable, but desired:
this way, we raise awareness of the new name.

I thought so. Maybe we should have commandp return nil for obsolete
symbols. (which-func-mode isn't currently marked obsolete, but it can be
easily enough.) make-obsolete already sets the byte-obsolete-info symbol
property, which we could inspect easily enough.
