I don't know what can be done a this point to change the terminology
in 2434. It's been in use for some 4 years now...
It would seem quite simple for you to take the text of RFC-2434,
edit the text appropriately to pick a more clear and accurate
term, then run it past the community for BCP.
well, the phrase "IETF Consensus" would still be embedded in several
other documents. are you claiming that it's simple to update these
also?
