I think you oversimplified the code merge process at Facebook. Their internal code review system (Phabricator) would automatically add tens of reviewers to your PR because you changed an important script authored by those people. Also, there are linters that would call out the use of potentially hazardous commands. Actually deploying the thing is another process that requires jumping through a series of other review hoops.

p.s. I had a short internship there.
