For pedagogic reasons, yes I do. It makes for a conceptually easier 
mapping between markup and the DOM and it helps catch unintended errors.

The one main drawback is the white space nodes between end tags and the 
next start tag, that makes walking the dom a bit harder. However, they 
should not be taught to rely on solutions that only work when such 
redundant nodes are missing.

Uhm, yes I think it should be served as text/html. (I never intended to 
question that.) I do not think the validator should say it's A-OK, though.

It's good to know that this idea has not died. When we have gotten OWEA 
off the ground I think it could be something for us to give some 
consideration. (My idea, I have not discussed this with my fellow OWEAns.)

However, I do not think that a pedagogic profile for the validator would 
absolve us from having reasonable conformance rules for normal 
validation as well.
