I'm confused why the correct course of action isn't to revert the commit, ask the author to re-open the PR for comment, and follow the process. Why the tortious apology?
If I wanted to interpret this in a paranoiac way, I would say that's because the author of the PR isn't apologetic at all, and in fact is quite fine with forcing a PR through the maintainers without their consent.
Hanlon's Razor, I believe it was.
And here, by "stupidity," I just mean the author didn't think about that.
Too often people are willing to attribute sinister meaning to what, in reality, was just a mistake.
