Is the latter better frequently enough? If yes, why don't we have it in 
other modes?

It's an investment in the future. Future users, at least. Or existing 
users who use some major modes and would benefit from consistency when 
trying out new ones. E.g. I don't use CC Mode often, and when I do, it's 
a whole new universe.

Pretty much what you suggested. Remove the binding and mention that in 
NEWS, together with the existing alternative.

Some users might be upset, most won't care, and some will be educated 
about the better alternative. The binding would also be freed for some 
feature in the future, like C-REPL maybe.
