But I also think that if a maintainer asks you to jump before submitting a PR, you politely ask, “how high?”
If trust didn't matter, there wouldn't have been a need for the Linux Kernel team to ban the University of Minnesota for attempting to intentionally smuggle bugs through the PR process as part of an unauthorized social experiment. As it stands, if you / your PRs can't be trusted, they should not even be admitted to the review process.
That's a pretty nice offer from one of the most famous and accomplished free software maintainers in the world. He's promising not to take a short-cut reviewing your PR, in exchange for you not taking a short-cut writing it in the first place.
