If it doesn't provide all you need then it's easy to involve other non-React code to make it all work. That's what's so great about it being a library - you're free to implement whatever pattern you'd like around it. For me, that's Flux/Redux (I use actions to call to well defined services) but it really doesn't matter. I think there's a list somewhere of patterns that are difficult / non-ideal for React but I don't have it in front of me. For 99% of use cases React really isn't going to be a detrimental choice as long as you choose a good pattern to surround it with.
