As Philippe suggested, it is mostly script related.
For example, one could use JS to plug an id on <html> so elements can be
styled depending on that hook.
#WeKnowJSisAvailable .widgetPanel {display:none;}
This is much better than using a class or ID on body as it will prevent a
reflow.
Note that because this is generated markup there is not really a validation
issue, but still, I think it's better to do stuff the DTD allows.
