Matt, your current implementation is sort of a mix of shallow (with respect
to private DM_Plex stuff) clone and deep/rebuilt (with respect to DM stuff
like defaultSection). I think it's worth making consistent, but safe
sharing semantics are tricky to specify. I think DMDA will be somewhat
involved regardless of the desired semantics.
