AFAIK there was simply no one who implemented it.

about your patch:

1st: you should also drop the line
             BOOST_UBLAS_CHECK (!preserve, internal_logic ());
if the preserve logic is implemented.

2nd: If the new size is smaller than the old size, some (old) index 
values may be too large and you should reduce filled_ such that
  zero_based( index_data_[filled_-1] ) <= size; 
(we should add this check to storage_invariants, too)
