It would be foolish to rely on Redux with no strong alternative. One of such alternatives is MobX, a state management library that is not so opinionated on mutations. MobX comes with as little boilerplate as possible. This is huge compared to Redux, which, being very explicit, requires a lot of boilerplate.
Here I must stop to remind you that the React ecosystem leans towards explicitness, that is, building apps without too many hidden mechanisms. You control the flow and you see all of the bits that are required for the app to go the full cycle of Flux. It's n surprise, then, that mainstream developers prefer Redux. An interesting fact is that Facebook Open Source is backing the MobX project.
MobX, being more implicit, can hide away some logic built around Observables and provide neat annotations to quickly enhance your stateful components...
