This is exactly the direction I want to take with Popper.js!! The part that sets the style to the DOM will soon be moved to a modifier/plugin so that it can be disabled and replaced with a modifier which just exports the coordinates.

That sounds promising. So conceptually you'd end up with something like popper-engine and popper?

Yup something similar
