nfsd shares the same sockets between all NFS versions. We can't change

That is worth mentioning in a documenting comment before nfsd4_dispatch().
I feel that we're adding yet another kludge to the NFSD infrastructure
to preserve an aging user space API and transport design that was built
for an era when all NFS versions would always use every transport and
address family.
I agree with Peter that we should make an effort to use the RPC
infrastructure as it was intended, in order to advertise the correct
services and transport capabilities; and update our user space API to
allow user space to have more fine-grained control over what the kernel
will advertise and run. But perhaps that's for another day.
