Right, the color the bubble is to remind us that features are missing, it's not a missing feature itself. RCS still doesn't support end-to-end encryption, and still requires carrier participation. There are still carriers that don't support it, and not all carriers support it equally. Google just managed to get the last major US carrier to adopt RCS this year so all of this about Apple being behind is marketing nonsense.
