Admittedly too many API's written with a RESTful interface are designed in such a way that async calls and callbacks aren't being taken advantage of, I think the only real thing REST misses out on, is what tech like RabbitMQ provide. And I'm OK with those being separated - to me, the more choice I have around techs used provides more competition for cleaner, easier configuration of said tech.
