No. What I said was, I had no interest (and I still don't). I'm not going
to edit, shepherd, and then implement something I don't think solves a
compelling problem lots of people are asking me to solve. That doesn't
stop anybody else from doing any OASIS work they like, or ignoring OASIS
and just writing it.
