Google's first duty is to provide their searchers with relevant search results... if I'm looking for information about proper safety precautions for in-home welding equipment, your (theoretical) little page about safety goggles with perfectly validating code isn't going to impress me when another site has a bunch of non-valid, but very informative HAZMAT data available. Google would be seriously straying from their primary objective, IMO, if they gave you position boosts for validating code.

Then again, maybe they could give searchers the option to turn on a "Valid Only" filter... the traffic data from that would certainly give webmasters an idea how many people cared about valid code in real-life search situations.
