Yes, <1h was a weak root password. All attacks I've seen directly were always user error. The point is effectively removing attack surfaces rather than enhancing security in needlessly exposed internet-facing protocols.
Relying on a 'sane password' is like seeing the stat '1 out of 10 cars is left unlocked' and commenting 'Yeah, but those people are stupid, I'd never forget to lock mine!'. While maybe true, it's irrelevant. It's objectively safer to keep the car in a private garage (Tailscale) than to leave it on a public street. Feel free to leave your car wherever.
