    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.
