Edge groups functionality - implementations in modifiers over time

One thing I've heard requested again and again in various youtube videos is how much "Edge Groups" are needed in blender (and are supported in other 3d apps).

Of course, no modifiers have functionality to support the use of them - however, that functionality can be added over time in a prioritized manner where it makes the most sense. One that would probably make sense as a starting implementation (of making use of edge groups) would be the bevel modifier so that specific edges can be beveled in a non-destructive manner. Of course, edge groups have many other uses, but have to start somewhere.

I think adding this ability to create these edge groups to the UI (and data structures) and then functionality to make use of them in say 1 or 2 modifiers would be a great start.
