What you are talking about is the Linux backend of the userland stuff
talking to  their kernel interface. The userland tools should get additional
#ifdef'ed stuff  to talk to the shared library implementing our interface.
Of course these changes should be handed back to the maintainers/developers
of the userland tools.

We have similar differences in *many* places. That's what the great standard
unix world is like.

This does not forbid us to make our interfaces similar or compatible if
their design is right from a technical point of view!
