Basically, I can guarantee that killing cookies would lead to 0% adoption of HTTP 2.0 forever, due to the same inertia that is holding Python 3 or IPv6 back. Doesn't matter if there's a better mechanism included that does the same job.

Provide session support in HTTP and still cookies for backward compatibility. If the support works right, people will migrate themselves.

…unless the EU forbids tracking and session cookies all together, but a ban on tracking cookies alone will be enough motivation already i guess.
