No, at least not in the terms you're thinking of here.  The constraints
that go into supporting servers in distros are very different to the
constraints that apply when building systems based around trying to
exploit the new capabilities of silicon that was taped out rather more
close to product launch than might be comfortable.  Some of it is just
bad practice and technical debt but far from all of it, these aren't
solved problems.

This isn't just something that goes on in embedded either - look at the
experience people have buying laptops with brand new Intel chipsets,
even running bleeding edge upstream versions of things it takes a good
few months after the systems start hitting the market for things to
become stable and reasonably functional.  

We do need to bring these worlds closer together, things like LTSI and
LSK which backport generic functionality from upstream are part of that
story in that they help avoid people reinventing the wheel in their
product kernels and make it much easier for them to move towards
mainline.
