As a member of the sending community I am very excited about the work Bron,
Richard and Co. have already done and have joined here to help continue the
work.

This proposal will help with dkim-reply and if done correctly could
eliminate the need for ARC and possibly even SPF.  We need a new way to
send email securely and this proposal seems to be on the right track!
