Which always seemed a bit ironic, considering those libraries are presumably intended to make state management work better if you really have to do a lot of it (i.e., have a large product).
At MPOW we have a bunch of state-managing components for complex cases, like multi-page forms or API-backed grids with tons of filters, etc. They take some effort to get the hang of them, but after that they save large amounts of boilerplate.
