I do not know of any companies or interested parties that is interested
in this. The ones that rely on 4.4.x right now are going to be dropping
support for it this month, if they haven't already from what I know.

So I have no resources to maintain this anymore, sorry, and I STRONGLY
recommend that everyone else just move off of it as well.

That is up to them to do, I wish them well, I think it is a loosing game
and one that is going to cost more money than they realize. Remember,
it costs more money and time the older the kernel is to keep it "alive".
It is cheaper and easier to use more modern kernels.

Not at all. It is barely alive as-is. If you _HAVE_ to maintain it, I
recommend only doing it on a very narrow way (i.e. limited functionality
and hardware support). That's the only possible way you will be able to
do this.

good luck!
