My main qualm with this is that not just QEMU, but every layer above then needs to either treat stats as a "dynamic" type unless they want to only handle providers that they know.

The main reason why I asked Mark to do all this work, was so that new stats and stats providers could be added transparently, and only new *targets* would need work all over the stack (but those are fewer, for example blockdev/netdev/iothread).
