This exists currently. However, we are debating how it should behave.
Currently the natural vector has a global order that matches the
original global order, but has the current partition. It could be that we
want a vector that matches the original partition, so we are discussing
this online.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
