To build something 1:1 with iMessage, there'd need to be a market the Pixel has a large share of. For something like FB, they tried with G+. And WhatsApp had first mover advantage.
They had other messaging apps that were maybe ok, but I've never known anyone who used them, and whoever did was thrown off when they made 999 other apps.
