I think that would be silly.

If it can be generalized, it can be generalized. But it seems unrelated 
to the current discussion.

project-find-regexp is both faster in most situations, works remotely, 
and provides a decent UI.

You're free to implement any variations of existing commands, and they 
can be good in certain situations, but we shouldn't prefer them over the 
primary command (which has had quite some work put into) for the menu 
placement.

That doesn't sound right. We put info into the manual to popularize it, 
not vice versa.
