I think more low tier output would be a disaster.

Even pre AI I had to deal with a project where they shoved testing and compliance at juniors for a long time. What a fucking mess it was. I had to go through every commit mentioning Coverity because they had a junior fixing coverity flagged "issues". I spent at least 2 days debugging a memory corruption crash caused by such "fix", and then I had to spend who knows how long reviewing every such "fix".

And don't get me started on tests. 200+ tests, of them none caught several regressions in handling of parameters that are shown early in the frigging how-to. Not some obscure corner case, the stuff you immediately run into if you just follow the documentation.

With AI all the numbers would be much larger - more commits "fixing coverity issues" (and worse yet fixing "issues" that LLM sees in code), more so called "tests" that don't actually flag any real regressions, etc.
