  I guess adding the InsertMode is fine.

  I'm not down on ever using DMComposite, I'm only down on always using DMComposite.

When we talked at the lab, you seemed rather down on using DMComposite, but I don't see a good alternative for e.g. equations in a volume coupled to equations on the surface.  In any case, should DMCompositeGather() take an InsertMode argument?  Or is there a different way you had in mind?
