Why not, but this may look weird to an implementor at first sight. At least, 
things would be consistent, though. The only strange thing is that the only 
way to put elements before the explicit grid would be to use this trick, as 
those cells are not targetable otherwhise, but this is pretty minor.

If a majority of stakeholders agree on this, so do I.
