Can you (or someone knowledgeable in Windows) verify that all of these are meaningful there? I'd expect it to be so with the possible exception of panon.
They don't have to all be cross platform. We can expose platform specific metrics via feature bits. We should only disable features that the guest has acknowledged.
But of course, whenever possible, we want metrics to be meaningful cross platform.
