Both IE 6 (https://lists.wikimedia.org/pipermail/wikitech-ambassadors/2014-August/000872.html) and IE 7 (https://lists.wikimedia.org/pipermail/wikitech-ambassadors/2014-September/000926.html) are no longer receiving JavaScript (and also any CSS served via JavaScript).
We should remove our IE 6 and IE 7 workarounds, as well as the gate for IE >= 8 (which is now done for us).
