DomainKeys was already made Historic when RFC 4870 was published in 2007. Look at the RFC status.
Indeed. Upper right corner of the page: rfc4870 <https://www.rfc-editor.org/rfc/rfc4870>
It is relatively common to have a working specification come from the community, as input to an IETF standards effort, and to publish the community specification as a companion document, usually as Informational.
Marking one as Historic is, I think, relatively unusual. As I recall, in this case, it was an explicit decision, as an informal encouragement to have existing users of Domainkeys move to using the (then) newly-minted DKIM.
