There is already an AF_IUCV for s390.
This is a scarecrow and irrelevant to this discussion.
And this is exactly why I asked that any arguments in this thread

No, TCP falls under the not simple category because it requires the
backend to have access to a TCP/IP stack.
I'm at a loss for words if you need TCP in the hypervisor, if that's
