Of course, the problem is that apart from single person projects those tend to be rare.
OpenBSD doesn't have a CoC and they openly even laugh at FreeBSD for having one, so it's pretty much confirmed they won't have one anytime soon.
C doesn't have one, thankfully one of the only languages left that troons are too afraid to touch.

But wherever else I go, either they have one, or might have one in the near future.
