It allows to move the core inside the topology tree to optimise
the cache usage in the case the host's hypervizor previously

moved the CPU.

The same command allows to modifiy the CPU attributes modifiers

s/modifiy/modify/

like polarization entitlement and the dedicated attribute to notify
the guest if the host admin modified scheduling or dedication of a vCPU.

With this knowledge the guest has the possibility to optimize the
usage of the vCPUs.

Hmm, who is supposed to call this QMP command in the future? Will there be a new daemon monitoring the CPU changes in the host? Or will there be a libvirt addition for this? ... Seems like I still miss the big picture here...

Or if this is just about to provide an API for future experiments, I'd rather suggest to introduce the new commands with a "x-" prefix to mark them as experimental (so we would also not need to go through the deprecation process in case they don't work out as expected in the future).
