>Should there be a 3DES "diediedie"?

Only if there's an actualy issue.  3DES is still very widely supported 
(particularly in financial systems and embedded), and provides a useful
backup to AES.  An attack that recovers cookie if you can record 785GB
of traffic isn't anything I'm losing any sleep over.
