I don't think it's productive to go over this all again because I've
done it several times over the last few months. Nevertheless, recognize
that you are arguing not with the HTTP specification but with one of Tim
Berners Lee's Web Axioms. The HTTP specification is just a reflection of
those axioms. Here are some references:

This isn't an HTTP issue. It is a web architecture issue.
