I'll look through this in more detail in a bit. But, I'm a bit bummed
out by the diffstat. When I see patches add a bunch of infrastructure,
I *really* hope for code simplification.

Looking at the diff, I think it gets there. The code you add is
simpler than the code you remove. But, the diffstat is misleading.

I'd probably address this disparity for each patch in the changelogs.
