This would be my bet too. One could easily imagine a future in which
garbage collection would compress data down and simplify the heap. This
could mean reordering in hash-like structures such as HAMT. Another case
could be to solve highly colliding terms by running a hash family and
rehashing in certain situations. If your code relies on the order, the
design space is much smaller than it is right now.
