Dear PETSc Team,

I am writing a DMPlexCreateNaturalVector routine in src/dm/impls/plex/plexnatural.c. What is the way to properly interface the call such as for DMCreateGlobalVector? In particular, do you want to unify the call with its DMDA counterpart DMDACreateNaturalVector of src/dm/impls/da/dadist.c?

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.

I forgot to point you to the discussion:
