Two systems are suboptimal for developers. It would be great if Apple and Google could get their heads together and find a way to interoperate. I don't mind the bubble colour... I'm OK with an Apple colour, Google colour, and an interoperable colour. It would be useful to signal what features might be available with each technology. What I would really like is for the interoperable solution to have a common API so I can programmatically sent a message to anyone (at least the two main players with an option for other phone makers — and also apps like Telegram — to join).
