I don't think we strictly _need_ to do this now, however I think it's a good idea given that we'll need to do it eventually and we can do it now and get people to consider implementing it more easily as part of a larger spec than later as a subsequent standalone. Doing it now gives it far greater visibility and should be relatively simple and quick to do.
