While not making a statement on whether vhost-user is technically
suitable in this case, I would note that we have a strong bias
towards "use facilities we already have rather than adding new ones",
because having multiple ways to do something in QEMU is more
maintenance effort and also confusing. It doesn't seem to me to
matter if vhost-user provides extra features your specific use case
doesn't need - just don't use them...
