It wasn't hard to keep track of compatibility with these older rubies, but since they made CI fail in a way that's odd, and probably not fixable, I am okay with not testing these in CI.
If we introduce an incompatibility somehow for an older Ruby, and you run into it, let me know and I'm happy to cut another release that fixes your issue.
