Wow, interesting. So, to access 3rd party cookies I need to access a document DOM object that has that 3rd party origin? But such a document is not always available, is it... Looks like the use cases targeted by that proposal are limited to an embedded iframe that wants to access its own domain cookies. I was thinking also about arbitrary doman. Like requestStorageAccess(targetOrigin, keys...)
