I really don't think there's much that can be improved to what you already made available Alex. It's top dollar as is.
I do think that the Intel'ers here need to either push work like yours to be more visible or come clean and tell everyone that the IoT kit and page is the way to go from here.
The problem in my mind is that people are being told to go straight to Mount Everest, i.e. Yocto.
It's like saying "Who needs Redhat or Debian, heck no, lets go make our own". Very obvious to me with the volume of people here with build problems.
