Thematically? Let me point at one old example that did what you're trying to deny: the Kempeitai: The Kempeitai might be as well one of the most insulting unit designs for a wargame. Conceived as an unit for the faction of YuJing it was nearly useless in the generic list, finding only a place in the JSA sectorial. From a design point of view it's a wasted slot. But the most infuriating thing was the fact it could be fielded as a merc by any faction, whenever mercs were allowed, with a profile featuring impersonation against any YJ army and d charges. Want another example? Rui Shi in Dahshat with an amazing special fireteam that the home army can't enjoy. Another more? WuMing enjoying a haris option in Ikari that is missing in ISS. I'm sure you can see the trend. So Saito lost the SO option in JSA after a year enjoying it? Well then it's time to bear up with it and adapt. Alternatively there's the option to play another faction or even quit the game if the player can't stomach this. There's only one person that can answer your question and that is Gutier Lusquiños, aka Interruptor, aka he who has the ultimate word about game design and rules. And he's quite busy to waste time showing up on forums, so it's never gonna happen. If you want your question answered you have very few options, which narrow down to mainly participate in the next Interplanetario and get the chance to meet him in person. Otherwise you're wasting your time with futile requests. Besides I would like to point out community is not entitled to get an answer about any change decision in the game. It didn't happen when Ko Dali moved from YJ to CA, it didn't happen when Alive team disappeared from the rosters, it didn't happen when Uprising hacked a full sectorial 15 profiles worth from its parent faction and was given no compensation; and it won't happen because of a profile option disappeared from a list after a year. Just accept that changes happen in Infinity and what it's given now can be erased later. Or move on.
