I'm not exactly sure how the work has been progressing in regard to repairing the room situation, but I myself have experienced no problems using my Horizon with the existing features which do work. It is possible to board directly into the cockpit as well as loading items and NPCs directly through the use of commands.
I suppose nobody has noticed, judging by the posts I've read here, but there is no reason to manually dock anything. The Horizon is equipped with a tractor beam, which means that as long as you own or are assigned everything, small ships and vehicles can be tractored-in from the cockpit. Likewise, ships and vehicles can be unloaded from the cockpit as well. There's really no reason to even be physically in the hangar or docking bays in order to use them.
