I think the technical aim of the document is fine, but it needs another
round just looking for editorial nits. I found small things like:

Duplicate parsing steps (#2 and #6):
https://tools.ietf.org/html/draft-ietf-httpbis-header-structure-15#section-4.2

and duplicate references. I believe the document may also need a collected
ABNF grammar. There are references to things like "item_or_inner_list" that
indicate there probably is a grammar, but it's just not in the document. It
may also be worthwhile to add a PEG grammar to the test repository before
publication, so that it's clear that the specification is straightforward
to parse with a recursive descent parser (I would use Pest[0]).
