This is from a discussion I had with Marshall yesterday (and Thursday) - even though we construct these things and then use them immediately, perhaps it would make more sense to not change the mesh itself over time but instead change the position field. That would make the same IO infrastructure work here as it does with everything else.
Setting up the position is difficult enough for surface meters that this isn't worth the effort - lets keep these meshes as-is and continue using the identity position.
