QML/UI framework reusability

[DragoonX6]

According to Tantacrul's video about the making of version 4 the component library is open source you encourage other applications to use it (previous link is timestamped to that quote). I'm interested in using it, but looking through it quickly it doesn't seem like the UI libraries are fully decoupled from the rest of the framework.

To what extent is the UI framework coupled to the rest of the framework? If I want to separate the UI parts for use in my completely unrelated application (different field entirely), how hard is that? Is there interest in splitting this off as an official musescore organization library?

Full disclosure: I'm not yet sure if the UI library is right for me, and if I want to use one of the built-in QML material design themes or not.
