I wonder from your post count whether you've ever witnessed one of Sun's "user experience enhancification" events. They're not pretty. While there's much to be fixed, there's still much that hasn't been broken yet. Perhaps it would be best if they just leave things alone.

wasn't it in the time before Llamas?
Such things were I guess considered a potential security risk as Sun initiated single signon and your login can now also be used to access other parts of the Sun online presence, some of which can cost you money.
Not sure, but that's a good reason to disable such things (and bring on session timeouts which seem to be partially effective here).
