I offered an alternative suggestion for how 'g' could work (prohibit 
free editing when the command finishes). Or perhaps some of the other 
suggestions could be taken and standardized on for similar circumstances 
('C-c C-g' might be appropriate since it's major mode specific).

I think it's a nice property that major modes that have this binding 
implement some special behavior for reverting. And all that do, have 
this binding.

But now, if a global binding is added, I worry that people might abandon 
that convention.

Isn't the answer to most such questions, 'enable global-auto-revert-mode'?

I do revert buffers explicitly from time to time too (especially when 
developing or debugging certain Elisp packages), but still not often 
enough to worry about having to type 'M-x revert-buffer'.
