If the Xeno ID ends up being used, you'll need to get a different IFF. Shooting Liberty capital ships that are stationed for the purpose of defending Liberty from the Rheinland threat will make us hate you real quick since you're intentionally weakening our borders. We frequently ally with ln to kill rheinland incursions in Texas. An exception to the "no shooting your own id" crap would have to be added. You'll also need to refrain from docking on Xeno bases or using our equipment. Then there comes the issue of not being able to shoot your own id which is a pain.
Tl;Dr idk man.
Edit: I see this was resolved already towards pirate id. I blame skypelag.
