I'll note that the spec also defines a "DEVICE ID of Virtio Cpu balloon device as 47". But
no changes really happened in the spec with that for the last two years (only the
id is reserved).

Maybe that's a good reason to keep calling it "memory balloon".

And hey, there's also the floating, pops easily kind and maybe someone
will use those with linux in some way :)

There is only one true balloon ;) the others can specify it as 
CPU_BALLOON. If that ever sees the light of day.
