Not like it matters to be quite honest, these embargoes only exist to give the lawful factions something to do and support a factions role play. I've seen zero number of people enforcing the consequences of said embargoes on themselves.
Its a matter of choice really. Do you care that your trade route breaks the laws of another faction? If so, don't do it. If not, have fun doing it. I don't think the development or admin team needs to get involved in temporary embargoes like the GMG/Kusari. Permanent embargoes like the Rheinland/Liberty or Kusari/Bretonian one, yes the development/admin team should balance those routes to match the risk.
