I meant the future of this approach, after there is the option to unfold volta 
repeats.

I was thinking that by doing the unfolding in the iterators
(as opposed to working on music expressions as \unfoldRepeats does)
it would be at least possible to expand volta repeats.

It would not be easy, because there are nonsense cases like
  << {s1 \repeat volta 2 s1 } {c1~ c2 d2} >>
and probably some very similar things that actually make sense.

It would take significant work to communicate between various iterators,
similar to the efforts Mike made to break slurs at repeats.
