Well, I think the main difference is that overlays are object, that is,
there is a struct Lisp_Overlay. There were some issues with how
intervals are grafted into a buffer if I recall correctly.

Hm, perhaps there is a way to make a struct Lisp_Overlay which just
points to an interval. I should probably have a look at that again.
