There is some amount of boilerplate with rolling your own, but I think people might benefit from rolling their own flux implementation when they first try to play with react. The best solution I think for this is to have multiple dispatches in your actions.

Create action -> action[dispatch 'action pending' -> async action -> dispatch 'action complete with data'] -> stores.

Keep your stores completely sync, and the data in a single object, and maybe have them all be pure functions, and suddenly there is no web of anything and theres a single source of truth, and bam. nice.
