I don't think lack of external adoption is a terribly useful data point
either way at the minute.  While the feature is controversial a lot of
the OSs will probably hold off on it (because it's effort to handle out
of tree stuff and folks are really busy) and there's not that many out
there which support random externally written packages (which is the
major push for exporting the feature to userspace) in the first place.
