That's the issue here.

Even if I trust you, I still need to review your work before merging it.

Good people still make mistakes.

What is the definition of trust if you still have to verify? How does "trust" differ from "untrust" in that scenario?

[johnnyanmac]

trust resudes the verification I suppose. Getting a PR from a trusted contributor would probably have me do a quick scan for obvious mistakes. And they'd know to keep the PR's small and on the right branch to help facilitate a scan.

a new person with a big idea on the slightly wrong (but reasonable) channel would have more work in verification.
