Hi Reto,

the document you discuss is describing the already-done-decisions of the 
TAG to a greater audience. The decisions have been made long ago and the 
document explains them. We cannot incorporate your feedback as it 
suggest changing the TAG decisions, which is against the goal of the 
document.

Your answer suggests to replace the whole architecture of the internet, 
including DNS and HTTP.
You may want to join the W3C and start a working group on this.
Otherwise, the right mailinglist to discuss this is semantic-web@w3.org

greetings and best wishes
Leo
