What are the applications/use cases for this library that weren't readily available before?

You can get the same functionality by using an existing state manager, a socket library, and your own tree diffing algorithm. This is just a baked pie ready to eat, along with some syntax sugar :) Here is a very simple example usage: https://github.com/mstdokumaci/stx-vue-example

I get the picture, looks really useful. Maybe the tagline "Batteries included data structure / state manager." Could be something more like "minimal web socket synchronized state manager" or something like that.
