No. All new devices should be fully qdev based.

I suspect you've also ignored a load of coherency issues, especially when not
using KVM. As soon as you have shared memory in more than one host
thread/process you have to worry about memory barriers.

Shouldn't it be sufficient to require the guest to issue barriers (and to ensure tcg honours the barriers, if someone wants this with tcg)?.
