And if the validator is updated to detect them, then they are just
going to find away around it. Its like the quest to defeat
popups. Browsers start blocking popups onload, sites start adding
popups to onclick events everywhere in a document (Sitepoint being a
case in point).

Trying to stay ahead of people who want an invalid document that
validates is pointless.

Users can input data (e.g. cookies, query string) before the document
is loaded.

No, we would both like to see the problem addressed, just by different
ways. You appear to think that technology can solve the problem of
users not understanding what the tools they use are for, I think that
education is the only sensible way.

That statement contradicts the rest of your claims.
