This document proposes two changes to cookies inspired by the properties of the HTTP State Tokens mechanism proposed in [I-D.west-http-state-tokens]. First, cookies should be treated as "SameSite=Lax" by default. Second, cookies that explicitly assert "SameSite=None" in order to enable cross-site delivery should also be marked as "Secure".
