We've discussed it here [1], plus seemingly all other DTs (though I
did not in fact check *all* other DTs, just a few from different vendors'
subdirectories) seem to put it last, so I think we concluded that not
standing out makes sense.. The DT spec itself does not specify where
it should go, but this could possibly be a good addition to it..
