This is an interesting assertion to make; everything else you say
follows from it, but I'm not convinced that this should always be true
for every single subsystem.

I'd love to be proven wrong, but as best as I can tell, the people who
did the earlier work have dropped the ball and nobody other than me
seems willing to pick it up.  I took a stab at merging their previous
work up to -current and the number and nature of the things touched by
the branch was such that it felt like the approach they took was not
entirely correct.

I'm exploring another alternative here.. I think regardless of what we
do here, it's going to be messy.
