we've deployed a page at our IDP that will delete the IDP's session cookie.

SPs can choose to redirect the user to this page if a user clicks LOGOUT 
at the SP site (after deleting all session cookies at the SP)

I believe there's also a version of the IDP page that asks the user 
whether or not they want to destroy the session at the IDP.

Would an approach like this address concerns from these SP operators ?
