In a way I like the notion that everything Edge or related is always in a container, but on the other hand with the Edge engine no longer supporting VML, VB Script, Toolbars, BHOs, or ActiveX in any way I am not 100% sure of the need. Edge compensates by embracing HTML5 fanatically. So far I have not run into a site that does not operate properly in Edge, I suspect because of the heavy HTML5 support.
Plus, Edge will very soon have a VS/HTML based addon model.
