On the MP topic: Back way ago, when it was discussed, nobody really had a great solid idea to to timewarp, and the game was in very early development. Now, KSP has grown. Part modules, lots of things under the hood to help. Then KMP happens. SQUAD actually probably takes inspiration from KMP to make the new multiplayer. Maybe the "its not posisble" statement was true- back then. Also, be aware that this is the inital server tests- not anything solid or "Actual connections between KSPs"
