Deacon,
I guess you are right, in a way that it would work. The only issue I can think of is that average / new user might get "surprised" if exported segment(s) are not lining up smoothly musically.

P.S. I was working on a piece yesterday and performed likely ~100 partial regens on different segments. Surely, more than half of these affected "tails" beyond selection. Which is a good thing, as parts didn't sound like a chopped loop salad which is common with some other software.
