I think the point is that serializing the entire react-router state into a redux store is in itself barking up the wrong tree, not that their approach is complicated or implemented in a buggy manner, per se.

I think the "still in beta" argument doesn't hold up so well. Many projects now stay in more-or-less permanent "beta", just as a sign that they're open to significant changes in the future.
With React libraries in particular, the ecosystem is still evolving so fast it seems relevant to note which are bug-prone, popular, etc, just to try and predict which will still be alive in a year.
redux-router is still in beta, so this isn't entirely fair.
