I'm trying to prevent anyone from ever dropping a table in production again or executing a delete without a where clause.

Essentially a PR review flow for production access, which allows you to enforce a second pair of eyes workflow. I was always a bit scared when I was on call and had all the power in my finger tips to ruin everyone's day. I think this helps alleviate the risk of human error significantly. Also helps with compliance of course.
