This makes sense for large-scale and widely used projects such as Ghostty.
It also addresses the issue in tolerating unchecked or seemingly plausible slop PRs from outside contributors from ever getting merged in easily. By default, they are all untrusted.
Now this social issue has been made worse by vibe-coded PRs; and untrusted outside contributors should instead earn their access to be 'vouched' by the core maintainers rather than them allowing a wild west of slop PRs.
A great deal.
