>you're assuming copy/edit don't bump mtime

Incorrect, I only assume move/rename of backup to original location doesn't change it's mtime (which it doesn't with default flags or from IDE or file manager). And I don't think this is a weird or obscure workflow, I do it all the time - have two versions of a file or make a backup before some experimental changes, and restore it later.

I used to do that some 20 years ago when I was learning programming, but now it does seem like a weird workflow when git exists and handles this case well.
