What prevents them from doing this?  We will take any code that meets
our standards, what format is this external code in?

If no one is using it in the kernel, it needs to be removed.  No
abstractions should be added that are not required by the in-tree code.

So this series should be accepted, _or_ the external code needs to be
submitted for inclusion.
