Session-Only Remember-Me cookie (Enhancement RQ)

[Lachezar]

In a couple of projects I had to use Remember-Me services with a session-only cookie.
The idea is to keep the user's authentication state across server restarts, application crashes and redeploys, and session time-outs. This provides a bit of enhanced user experience.

I used to do this with a TokenBasedRememberMeServices subclass, that would always add a cookie, but it would be session-only if no remember-me trigger parameter was supplied, or persistent (as per default behaviour) if the trigger parameter is supplied.
Now I am using xml schema configuration, and found it hard to use a sub-class.

Request For Enhancement:
Add a flag to add a session cookie if long-term cookie is not required.

Your session cookie is supposed to go away when your session ends. How would the this work without making the session cookie not a session cookie?
