Can you illuminate more clearly what the unintended consequence is for the 
server maintainer is caused by sending the cookies with the request?

with cookies.  There is no same-origin policy for cross-site IMG, FRAME, etc 
requests with cookies.

As I outlined in my "to cookie or not to cookie" email, the concern isn't that 
new attack vectors are introduced. The concern is that servers will enable 
access control without realizing what it means.
