Consider this:

  1. The Dom stores children in a list
  2. Adjustable allows patches on a map showing kv-pair rearrangement
  3. extensibleListWidgetWithSize spoofs keys for a map solely widgets are laid out in the right order.

If reflex-frp/reflex#299 is ever done, we could remove the map entirely.

Even without that, it's possible to use tons of "with move" patches (http://hackage.haskell.org/package/reflex-0.6.1/docs/Reflex-Patch-DMapWithMove.html#t:PatchDMapWithMove) to perhaps get a slightly more efficient result. (Still O(n) not O(1) browser operations, but at least individual kv-pair widgets don't get redrawn.)
