FWIW, RCS group chat on Android being horribly broken is actually a feature if you have kids. I've spoken to many parents of girls in the 7 - 13 age group (and have two myself), and the amount of drama and bullying due to iMessage group chats is several orders of magnitude higher than what kids with Android experience.
I actually think iMessage group chats should have a minimum age limit, from a kids perspective they are no different than Snapchat et al.
