OSM tile grid is (like all of our other existing layers) based on the maxExtent
of the layer. Changing the maxExtent would change the extent of the tiles, and
then nothing would line up. 

If you are interested in changing this, check out:

  http://trac.openlayers.org/ticket/2741

Which has some code and discussion of the issue.
