In 2008 there were two proposals

https://datatracker.ietf.org/doc/draft-fuller-240space/
https://datatracker.ietf.org/doc/draft-wilson-class-e/

where the former was agnostic about how we would eventually be able to
use 240/4, and the latter designated it as RFC 1918-style private space.
Unfortunately, neither proposal was adopted as an RFC then, so we lost a
lot of time in which more vendors and operators could have made more
significant progress on its usability.
