To be entirely fair "sorta working, solving a problem but not really all that great for the rest of the codebase" PRs are human thing too.

The problem is AI generating it en masse, and frankly most people put far less effort that even your first paragraph and blindly push stuff they have not even read let alone understood

Well, it's not terrible at just getting your bearings in the codebase, the most productive use I got out of it is treating it as "turbo grep" to look around existing codebases and figure out things
