This is going to leave so many people by the wayside. (Pun totally intended.) Late 2020, my jaw dropped on the floor when a developer from CERN showed up and said that X11 support was needed in ContainerSSH for their use case and then developed it. (The LxPlus service, which acts as a dev host for researchers.) I thought X11 forwarding was well and truly a thing of the past.

Yes, I know that waypipe is a thing, but it needs to be installed on both ends and I haven't seen any mention of non-Linux support either.
