Wonderbar:

 I think Porsche should offer a "rear seat delete" option and an attractive rear compartment storage area with a Panamera like retractable cover...

They have - but with the emphasis on driving over shopping, they're using the extra space to pull the engine forward a bit more than the 100mm on the standard 991, and, with tradition in mind, they're going to keep calling it the Cayman.
