I had this exact issue at a last company. We had a system that tore down and rebuilt our entire clusters to updates QPS estimates. It was the right idea and the right approach, but it was a big gnarly ball of code that broke frequently, requiring the steps it got stuck on to be done by hand and the code fixed for next time. So anyone working on it still had to know and be co dude that’s executing any arbitrary manual steps as well as understanding the code enough to fix it (or get the expert involved). I’m doubtful it was a net positive in that state.
