regarding gypsies/yakuza, the yakuza has a big foreign population too, mostly korean. It's not really any more entrenched than crime here, so much as westerners looking at it with romanticised/ill informed views.
as for the other stuff, eh. I don't think KNF or KSP being red to junkers is really in rp, but it works in as much as it stops junkers docking kusari lawful bases. and yeah discovery kusari is moving back in time from vanilla kusari regarding isolationism.
