suggestion to improve cookieless session state

Whidbey finally gives us cookieless forms authentication, which is a great new feature. But, to make it even better the .Net team gave us more than a simple true/false setting. Instead, we can set the "cookieless" attribute of the <forms> element to "UseUri", "UseCookies", "AutoDetect", or "UseDeviceProfile". This level of control and flexibility is amazing, but it got me thinking... why not add this same feature to the <sessionState> element? Currently, the "cookieless" attribute of the <sessionState> element only accepts a true/false value. Would it be possible to extend it to support the same set of values that the <forms> element now accepts? Of course, it would still have to accept true/false as well for backward compatability.I think it's a great idea.
