This is one of the arguments for polyrepo: different sources have different sensitivities. Code ending up in production needs to be reviewed, so enforce reviews.

Docs do not.

So what results is either allowing developers to push (but not force push) directly to main (you can always push revert commits if needed), or a PR process that exists to enforce linters and build-ability, but if those pass, allow the developer to merge independently, without human review.
