A protocol based mechanism has the advantage of being more robust in the face of poorly written block backends so if it's possible to make it perform as well as a plugin, it's a preferable approach.

May be hard due to difficulty of exposing guest memory.

If someone did a series to add plugins, I would expect a very strong argument as to why a shared memory mechanism was not possible or at least plausible.

I'm not sure I understand why shared memory is such a bad thing wrt KVM. Can you elaborate? Is it simply a matter of fork()?

fork() doesn't work in the with of memory hotplug.  What else is there?
