I've become one of them. It used to be that it was safe to experiment, because anything really damaging could be undone (which is an important part of discoverability). At some point, that stopped being a thing I could count on, so I've come to view experimentation as a risky thing.
But those nags don't solve the problem. They're really annoying, get in the way, and are rarely actually helpful. Nowadays, when they come up, I just close them without reading and get a bit irritated.
