You can commit it if you want; I don't care what goes into the mobile directory.   If/when it's promoted to the top level, so it can be used by desktop too, then it needs to be upgraded to be accessible, and also probably to have a hover effect on the stars like http://download.dojotoolkit.org/release-1.9.0/dojo-release-1.9.0/dojox/form/tests/test_Rating.html does.
