Why HTTP/2.0 does not seem interesting (2012)
  In my view, HTTP/2.0 should kill Cookies as a concept,
  and replace it with a session/identity facility, which makes 
  it easier to do things right with HTTP/2.0 than with HTTP/1.1.

count me in. Cookies are a huge waste of bandwidth and freaking annoying here in Europe as you cannot visit a site anymore without being warned you are about to receive yet even more cookies.
