Unfortunately this is a sign that the systems by which PRs are shipped need serious inspection.

For example in incident management, the industry settled on blameless postmortems. Blame is pointed at the systems which allowed incidents to occur, never the human(s) who triggered the incident. "Just don't make that mistake again" simply doesn't work. Humans make mistakes!

There are too many stakeholders in a product this large, even if every one of them wishes it were not so. The systems by which this PR shipped need serious inspection.
