I'm pushing this back to the next milestone for now. I would like to see this go in but after working on it for a day I feel like there's room for improvement in terms of naming clarity. I've gone through it a few times and caught myself getting confused with some of the functions/settings.

Maybe a unit test to ensure that backward compatibility works ? I know that if we end up breaking it quite a lot of production systems might just burst into flames.

This is off topic, but - I'm helping colleagues set up graphite & friends, and came across this PR (and related threads). I wanted to say that the maintainers did a great job managing the (distracting) side conversations.

In addition, I've been trying to come up with replacement words for black/whitelist, and your choices are great!

Thank you for this wonderful project.
