EFO was inspiration for 6CIO, but is different from 6CIO in that it is about flags promulgated by a router (and therefore can only be used in an RA).
6CIO is about the capabilities of the node sending that option.
That's why they are not the same thing.

6CIO is indeed meant to be general enough to carry other node capabilities that are relevant to a node-node situation.  ROHC-over-802 could have used it.  That's why I'm proposing creating an IANA registry. to make the other 47 bits available for other uses.

I'm completely neutral to whether GHC's compression scheme and 6CIO should be done in a combined draft or separate drafts.  In the latter case, stealing more text from 5175 is an obvious thing to do.

Is there anything that could/should be generalized about 6CIO?
(Without making it more complex, please.)
