Is this still needed?

ES6 has official promise support, and there's a 2k polyfill.

probably not, but for the most part I am not going to go through the effort of destroying it.

I don't disagree with using new(ish) things like ES6, but we've already productionalized a fair amount of code on this module and find no reason to change to a new implementation. For now, this is still working for us.

Cool. =)
