I mean - yeah, honestly, god forbid. Requiring manual saves with limited change history (or none at all) was the bad old days. That was bad UI/UX, literally everybody had a “oops I forgot to save” and a “oops I saved and I didn’t mean to” horror story. Things are better now.
I wouldn't say it was totally awful. At least, prior to having an Undo option or perhaps an undo but that can only go back 3 steps, saving as before making any large changes was a pretty common workflow. I might end up with 50 versions of a document numbered incrementally by the time I was finished. that is still a necessary workflow for certain types of documents. I don't necessarily want everything saved automatically all the time.
