mentions:
Symfony 3.0 is more decoupled and more reusable than ever

I noted that https://github.com/symfony/symfony/blob/master/UPGRADE-3.0.md does not have a section for Sessions.

Recently I ran into some issues when working with Symfony classes related to Sessions. It seems Symfony2 sessions are not fully decoupled from how PHP handles sessions internally. Is this on the radar for 3.x? Primarily I'm thinking this decoupling could make it easy for projects like https://github.com/reactphp to expand into things like long-running HTTP server processes, and putting frameworks based on Symfony Http Foundation classes on top of these servers.
