Not the parent but I've seen this scenario a few times. Essentially what you get is random groups of devs (often you never even knew they existed or were messing with your DB) who mount a DoS attack (not their intention but that's the result). Long lived transactions, unindexed queries, unexpected deadlocks, etc etc. Worst thing is their reaction is that your database sucks. So no amount of education will fix the problem. They think you're the problem. So you end up with a defensive architecture where the blast radius for any single act of stupidity is limited.
