The changes to the ABNF are good, and they resolve my concerns from -00.

I note a remaining problem with the ABNF that I missed the first time:

   n^(a)m element = ( n(*LWS element) *o(*LWS a *LWS element))

The first clause on the right is incorrect: it specifies <n>
occurrences of <element> with *no* <a> between them.  As you add that,
you need to make sure to get the cases where n=0 and n=1 correct, as
well as where n=m (I think that last one is already OK).

This points out the difficulty of getting such a general list
construct defined correctly, and shows why it was removed.

I agree with Tony that if you can't include examples of how we should
have had this before, it'll be hard to convince the community and the
IESG that it's needed now.  We can always come up with things that
*might* be useful, but part of the challenge is keeping the language
as simple as possible (and no simpler).
