What state should be able to have its keying relaxed?

This issue ties into the Storage Access API, but is also relevant here as it has implications for the architecture of the affected pieces of state.

Firefox has an implementation where Cookies and all of Storage go between having additional keying and not having additional keying depending on the Storage Access API.

Safari allows Cookies to go between blocked and not having additional keying (i.e., first-party access).

I'm not aware what Chrome is planning here.

I think this is leaning toward storage + cookies, but properly formalizing that is still work in progress.
