I would like to suggest a set of new directives for the content security policy which would allow the site to limit access to cookies. 

This may be is three forms (first being the most important):
- cookie-src (read/write)
- cookie-read (readonly)
- cookie-write (write only)

The main reason to add this directive would be away to allow site owners to ensure that their content policies align with the technologies and tools used on the site both with client run scripts and server side cookie handling. 

Other benefits would be greater security, specially around limiting data tracking to one intended parties / scripts.  Additionally greater possible transparency to the user to how cookies are used.

Thank you for the consideration,
