This was designed for any file save.

From what I know (correct me) magit-wip-mode hooks into editor saves. UNF hooks into the filesystem.

magit-wip-mode is great if your only risk is your own edits in Emacs. UNF* exists because that's no longer the only risk; agents are rewriting codebases/docs and they don't use Emacs.
