Indeed this was a mistake, and I fixed it on master. Most likely it didn’t affect anyone unless they did a fresh install, because sshd_config previously had it uncommented. Anyone running RELEASE wouldn’t have seen it.

The default on master is to not enable X11 forwarding. The sshd_config(5) manual page describes the reason for this default.
