I think bringing a sane extension model to Edge is a bigger deal than any of the other improvements that Edge is making over IE11.

For a couple years now, I would have instantly switched to IE on my touch enabled Windows machines if there were equivalent versions of my Chrome extensions available for IE. Overall performance, especially during touch scrolling and zooming, and memory footprint has long been dramatically better in IE than any other Windows browser (though Chrome seems to be trying to close that gap a bit lately).

If converting a complex extension like RES was really "easy to convert" with "only a few changes", that's going to be a very interesting development.
