As someone said a long time ago (way before the LLM craze) "bad developers love new projects, they can write terrible code, take praise and zero responsibility, then toss it to the maintenance (actual) team who has to deal with it".

(Context: in at least 2 companies I worked at, it was a common practice to have a "development team", usually with knowledge of latest tools and frameworks, but very little knowledge of processes or industry, and an "application team" that maintains the software long-term, and deals with the processes and users directly)
