Yes. Unfortunately.

Indeed user feedback is really required.

Please check:

It's for "drivers" and "filesystems".

You don't need to modify the kernel infrastructure to add drivers and
filesystems - but you need to change infrastructure to add new networking
functionalities.

Therefore i don't think, that this would work with the staging approach.

Btw. how can we gain more interest and users to the evaluation of Kurts j1939
stack? I remember about 3 persons asking about it (even about details) - what
happened to them?
