Not sure what that has to do with it, unless it was just a general complaint that no one develops anything for your phone. If the kernel for your device has been released, you can build vanilla AOSP fairly easy by pulling the general AOSP source matching your latest OTA and also pulling the proprietary drivers from your phone and building the kernel.

There's some guides out there on how to do it, but would have to look around for something specific.

Of course that also means you have to have an unlocked bootloader as well or the above is kind of moot.
