Thats the AI ID, it should be the only ID that lets you fly this ship without a huge energy nerf that would render it useless.
I always considered these ships to be Alien made AIs, so you could RP that pretty well.
The ID has a lot of restrictions which sadly dont make a lot of sense in my eyes. But people have abused these ships in the past to a point where it wasnt funny anymore, so thats why we have ended up with that ID.
