I don't think this is really much realistic, Rarely does normal CHP use a vest, They only wear it under their shirts. This would be more realistic if they added a CHP SRT Team and they put a CHP Vest into the SRT Team.
The thing is, RPD is a Whitelisted team while CHP is not, People might think someone breaking rules in RPD that just bought the gamepass is a Whitelisted member, Meaning they will cause problems that are not needed.
I like some of these suggestions even tho they are made with AI (No Hate), Some of these are not good ideas like Staff Count, If someone wants to break rules or exploit they can clearly go into a server without staff.
I am pretty sure you do as I bought the CHP Gamepass (Old Old One) And I still have access to CHP. Meaning if you bought the SRU team you should have access otherwise, Maybe they only did the exception to CHP and you have to buy the subscription.
