It wont matter in the Colonies. Not while the Empire remains intact at least. We can hope that the Imperial laws will continue on even when/if the Empire falls.
But the hope is to give the infiltrators freedom of travel. They will be allowed to attack anyone on the bounty board... Not complete diplomatic immunity because they can still be punished when caught (although I do hope to find agreement on how bans can be bought so that infiltrators do not have to leave once they are banned everywhere)...but still its a good way to get them stronger.
Sound like you expecting the Empire to fall after Queen Valakyrie term as the Empire first Empress(the fall of Rome Empire anyone?
)
My character Ash likes one fact about the Empire; supposedly the aggressor realm will be declared war by the rest of the Empire realms. And spared from destruction and what-not
