Both actually. I.e. there are political reasons why
upstream doesn't want to incorporate it and it would be
a lot of work to spoon feed small portions upstream while
turning a decade old technology into LXC++ :)

We defined certain interfaces more than ten years ago and
they have proven to be a stable and reliable construct,
but they are not what modern kernel interfaces look like,
so chances that those get accepted upstream are diminishing.

We also do not have the manpower to send a patch dozens
of times trying to make kernel folks happy :)
