Sounds ok to me.

Server-side applications should probably implement that in a way such
that just one session (identified by a session cookie or whatever)
gets logged out -- in contrast to all sessions of a user.
The user might be logged in using 2 different browsers and might
want to log out in one browser but keep the session active in the
second one.

And I'd probably want a same domain policy for the logout ping be
implemented in the browser.
