I'm still trying to wrap my head around Redux itself. But generally, I think simplification is always a good thing and modularizing this whole action, action-creator, reducer stuff into easily shareable components (pardon the pun) seems like a worthwhile goal.
Standardization is always welcome, especially when the sheer number of conventions are starting to introduce difficult to understand complexity. To me, Redux is such a case. It is hard to convince new developers of the benefit versus the massive learning curve, so this proposal seems like it could help us out here.
