@andrewheard, as far as outstanding TODOs for this PR, it's mainly to add back the existing public API to make this non-breaking, right? Anything else?

@ncooke3 This now has the existing public API to make it non-breaking but still need to fix the tests. Better names for the new APIs would also be good.
