This is not the case in any prior Emacs release. This is a (new) feature. The behavior change was in Emacs 29, where we have this in NEWS: ** Explicitly-set read-only state is preserved when reverting a buffer. If you use the 'C-x C-q' command to change the read-only state of the buffer and then revert it, Emacs would previously use the file permission bits to determine whether the buffer should be read-only after reverting the buffer. Emacs now remembers the decision made in 'C-x C-q'. The change was (briefly) discussed in bug#35166. If you want back the previous behavior, you can define your own function that is the value of revert-buffer-restore-functions (e.g., set it to nil). > I bind this command to F5, so the key reverts, as on Windows: > > (defun revert-buffer-no-confirm () > "Revert buffer without confirmation." > (interactive) (revert-buffer t t)) > > Useless now. You can change that trivially to restore the behavior you expect.
