The trouble is there are multiple things a user may want to do and
which one is a hard choice to make. If you have some narrow layer with
a specific image and application, that is easy. If you have a general
layer like meta-virtualization, it is unclear which target(s) a given
user may want. nodistro/poky face the same challenge, the thing the
user might want "depends".

I believe if we implement and do something, we need to do it well and
it does need to have a specific target/focus and use. If this
functionality is too hard or inappropriate to use for too many of the
application areas, you have to question whether we should be doing it
at all...
