Hi Benoit:

Thanks.  The question it in turn raises, however, is whether a crash
course on TS and AS intricacies is a worthy answer to the doubts that
those documents' differing categorizations might generate.

In addition to what SM pointed out, let me note that it was a WG
decision to proceed that way.  See e.g.

Possibly both, or the AS and the 6449 sections it refers.

They're not in conflict.  However, the MAAWG document is clearly
focused on quite large mailbox providers.  Unsolicited reports, that
were relegated to an appendix, have been expanded so as to bring abuse
reporting within the reach of mailbox providers of any size.
Unsolicited reports can be viewed as auto subscriptions to a feedback
loop stream of solicited reports.  RFC 6449's detailed descriptions
apply to the latter topic.

Authentication failure is a somewhat unrelated use case, factored from
other WG documents, that was conveniently added here later.
