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. If you think that process is too heavyweight to fix this, then that would be an existence-proof that even IESG members believe the IETF processes have become too cumbersome. Please do fix.
