This is one of the ways of using it, via a backend running in host
userspace, maybe there are other ways of making this work which I may
not have explored, like handling this within qemu.

The protocol hasn't changed in a sense on how it can be used. Yes few
things have moved around, new operations were introduced, but nothing
that will make a change at this level. We are trying to use the
protocol in one of the possible ways and yours can be different.
