Off-topic, I'm kind of surprised it took that long to fix it (if I am
parsing things correctly).

I believe Stephan Mueller wrote up the weakness a couple of years ago.
He's the one who explained the interactions to me. Mueller was even
cited at https://github.com/systemd/systemd/issues/4167.

It is too bad he Mueller not receive credit for it in the CVE database.
