In the parallel universe where I spent most time everyone
now need to learn how to make their things to work
out-of-tree. And there is not much of business case trying
to fix and improve core parts of linux. The turn around have
increased a lot and there is no edge doing it.

Things have changed. Once upon a time the community was
happy if it could get hardware specs.
