I had almost forgotten that single-level undo was ever a thing. I'm sure there are some applications still in production use that don't support multi-level undo/redo though.

Such as the base OpenBSD vi, which only supports a single-level undo, which I am using at this moment (and still learning how to use, after a few decades). vim got curb-canned a while ago due to various "that's nice, but how do I turn it off?" additions, in addition to having more code in header files than vi has in total. vi meanwhile is pretty bloated though has ex filters which are a huge step up from the standard editor. Multi-level undo? Don't really need it.

  But hey, at least it’s POSIX compliant! In that respect, anyway.

  For what it's worth obsd vi (nvi) has multi level undo. it is just the slightly awkward 'u' to undo/redo then '.' to repeat the undo/redo.
