Remember back in the early days they wanted all agnostic tags and no specific rendering or design stuff. You can request it be bold, or a heading, but I would decide how a heading or bold looked... that quickly gave way to the more prescriptive (designed) web, with the site controlling how a h1 looks ... which then gave way to the application web, where web sites use scripts and act as small applications.

Disabling JavaScript at this point is like disabling CSS IMHO.
