This resonates with me. I use undo/redo up to a point, but eventually I just reload the file (which I'm saving frequently) or just check it out (from git, mercurial) again.
Right - using undo/redo for quick or ephemeral changes, before solidifying into something (more) permanent feels very similar to me to making a bunch of small commits while working on/exploring something before cleaning them up into semantic chunks with a rebase.
Maybe there’s some implicit idea here like treating a commit as an aggregate of a bunch of atomic actions (i.e what undo/redo act on)
