There's only a couple of contributors to my code that I will take without
looking deeply at what it does. And those are well respected developers
that many other people know.

I'm skeptical of all static analyzers, as I've seen too many good ones
still produce crappy fixes. I look even more carefully if I see that it was
a tool that discovered the bug and not a human.

The one patch from Greg's reverts that affects my code was actually a
legitimate fix, and looking back at the thread of the submission, I even
asked if it was found via inspection or a tool.
