Can you at least summarize where the drafts are in the process, and if they
require changes to senders, mailing lists, receivers, or all of the above?

Are the proposals (which I guess are not yet adopted) complementary, or will
a beauty contest be required?

I think that ietf@ietf.org needs to know if we'll have a solution in time,
or if the secretariat needs to be asked to deploy mailman 3 sooner.

The very rough consensus a year ago was that we should wait for DMARC to do
something, and here is something.
