The change is turning me from someone who writes pretty good reliable code, to someone who has to read and review pretty bad code. If you think this is an improvement, you're nuts.

It is inserting a pretty unreliable middle-man know for errors and hallucinations, that often just goes down and stops working for reasons we can't control into a workflow that has worked well for a decade, and we're paying extra to really break-even on the time spent creating new code.

Just because "everyone else is doing it". Not because it's proving to be a boon in productivity.
