x86 PVH is completely obsolete - it was intended for legacy PVH before that idea was abandoned. There was an RFC series for ARM in 2015, but there is plenty of outstanding work which hasn't been done yet. No functional change. New types can be (re)introduced with the code which actually implements them.
