The issue I linked has a very good analysis of the UX issues and several suggestions for fixing these. They went with a minor iteration on the original message box, which not only includes a clearer message and the number of files affected, but also defaults to not touching untracked files (while preserving the option to delete untracked files as before).
I think that is already a requirement? As a dev I hated that we had to make what is essentially a day one DLC, which isn’t a good look. ”Look, they lock content behind DLC, which they already have, it cost them nothing”. Players extrapolate from that to other content we release later, content we actually haven’t even designed yet. Ugh.
Well, making a season pass is crap too, but there was no way to talk the publishing department out of that.
