There's no shortage of cross-platform chat apps. The hard part is getting people to use them.
In Europe, WhatsApp managed to secure market dominance; virtually everyone uses it, even people who would rather not. In the US, it seems like only iMessage has significantly displaced SMS. Google probably could have equaled that when it made Hangouts the default SMS client, but chose not to follow through.
I gotta admit, I like the RCS features. I'm starting to think the world at large could use a messaging app switch both I phone and Android. I just want platform independent features to work seamlessly.
