Since Aoi is a failed and now irrelevant faction without the ID possibility and this really only applies to Faes, I will mention their case.
We had an issue with that multi ID on [FLG]. We were there when Faes was conceived as infected mercenaries/freelancers flying freelancer ID lead by gallic character. All were Fae tagged, we did multiple events, hauling contracts, RP with them taking them as mercenaries.
When they got officialdom their members kept using Fae tag, on freelancer ID same as before - so we roleplayed with them as the allied mercenaries we have known them as for months - but apparently that was wrong, suddenly we were meant to pretend we don't see their tag, their member(s) even told us to stop roleplaying with them as we had before - it was very confusing, still IS confusing and any interactions just ...fizzled out as this was all so confusing, all that roleplay down the tubes apparently? We still have no clue what to do, the rules are ....awkward in this case.
But, on the flip side, you do need to give a chance to have activity on the faction at the same token - the pawn ID is ridiculously weak. Being an OF is not only useless but actively detrimental thing to most factions. But Wild absolutely need officialdom to be able to exist, and forcing Faes to fly non-nomad IDs without the tag would make their life impossible and shouldn't be put upon them.
I do not see a straightforward solution here. If there is talk about changes, it should be co-designed with Faes as they will be the only ones impacted by this.
