At this point in the patch series I agree, but in later patches we
take advantage of nd bus services.  "[PATCH 15/21] nd: pmem label sets
and namespace instantiation" adds support for labeled pmem namespaces,
and in "[PATCH 19/21] nd: infrastructure for btt devices" we make pmem
capable of hosting btt instances.
