The key word was unarmed ship...I really don't think that "idea" is going to go down very well. That's a play mode more or less like a private group that agrees not to kill each other. I 'kin hate the pointless murderhobos who attempt to gun you down without so much as a "howdy neighbour" but I think they were always intended to be part of the game.
PvP is still very much a thing, but you can't kill an unarmed cmdr.
