Do you have a concrete user in mind?

i.e. I am asking because the kernel, in general, requires a user (in
mainline) for code to be merged. So maintainers normally don't merge
code unless it is clear who will use a feature upstream -- please see
the last bullet of:

    https://rust-for-linux.com/contributing#submitting-new-abstractions-and-modules

Thanks!

Cheers,
