We either let webmasters serve up broken sites, and therefore have to program browsers to accept any old junk - which will lead to more and more browser exploits OR we tighten things up so that browsers are more picky in what they allow. If that means that broken sites will display broken, then so be it. The onus should be on the webmaster to follow the standards, standards which have been around for more than decade now.
