This makes a lot of sense.

I suppose what we need to think about is the bigger question of why
people/companies/managers are so worried about working upstream
that they will go to lengths to avoid it and jump at any chance of
raising a wall of abstraction between their internal development and
the in-kernel software development.

I think of this as vendor/community couples therapy or something,
there is some form of deep disconnect or mistrust going on at times
and having worked on both ends myself I would think I could
understand it but I can't.
