(info "(elisp) Key Binding Conventions") says C-c [^[:alpha:]] is
reserved for major modes (paraphrasing).  IIUC this binding for
revert-buffer would be global, so the C-x map would make more sense?  I
think?

C-x g would make the most sense under that assumption; unfortunately
magit-status has been using that for years now…
