Enhancement Description
RFC 6265-bis (https://datatracker.ietf.org/doc/draft-ietf-httpbis-rfc6265bis/) is currently a draft but outlines cookie name prefixes, in particular __secure- and __host-.

This should only be relevant for the client, as it should discard prefixed cookies if they don't meet the required criteria.
On the server, applications decide the cookie name, and should set them with the proper attributes.
