No. You can't drop anything from UAPI, used or not. Doing so will
break the compilation of any userspace that, for any reason, references
this value. We cannot reuse this value in the future either, as it would
create a we wouldn't know which device to create.
It is pretty unfortunate that PV time has turned into such a train
wreck,
but that's what we have now, and it has to stay.
