I know one of the most common reasons I push back on things is that
people either aren't using existing subsystem features or should be
adding new ones.

I think this depends a lot on how much of the work is factored out into
the subsystem.  Once you've got a lot of code factored out into the
subsystem I find the balance goes very much the other way and it becomes
much easier to have code in the subsystem than in the drivers - it
reduces minefields for refactoring so much if you don't have to worry
about special cases and well written drivers start to look much more
