If we used the #rule, it wouldn't be an ABNF conforming to RFC5234 anymore.

I have no problem in working on generating and publishing it 
unofficially, but I'm not sure how to make it part of the official spec. 
Any proposal for that?

Everything in an RFC is normative unless stated otherwise (as far as I 
can tell).

The ABNF appendix is auto-generated, thus I don't see how it can get out 
of sync with the rest of the spec except by us, the editors, screwing up.
