Yeah, that is a tradeoff - globalized state makes a lot of scenarios easier, but does make complete encapsulation and reusability harder.
Most of the third-party "Redux-connected component" libs I've seen provide a reducer that they expect to be added to the root of the state tree under a specific key name. Works, but it's not ideal. I've seen a few that let you provide a selector or key name when you initialize the library, so that the library is more flexible in how it's connected.
There's been a lot of discussion of various approaches for implementing fully encapsulated/reusable Redux-based React components in Sebastian Lorber's "Scalable Frontend with Elm or Redux" repo [0], and my links list has a section of additional articles on the topic of encapsulation with Redux [1]. My Redux addons catalog also has a large section for libraries that implement some form of per-component state or component encapsulation in Redux as well [2].
So, it's not impossible, but it does take work and there are tradeoffs either way.
