If you're sure, maybe.

But I would imagine that users of Emacs 28 and earlier would rather 
enjoy the new command (with a 'g' caveat) than have it disabled.

As a safety measure, in older Emacs you could also set 
'revert-buffer-function' locally to something displaying an error.

I don't remember using 'g' in ibuffer or list-buffers much anyway. But 
that depends on one's habits.
