If I may change the topic for a moment ...

I'm working on some stuff for ICANN to help people get EAI mail working. 
One of the underspecified bits of EAI is how authentication works with 
SPF, DKIM, DMARC and now, I suppose ARC.  There's a bunch of places where 
one needs to make arbitrary decisions about what's in ASCII (a-labels) or 
what's in UTF-8 (u-labels.)  I did a draft about it last year:

 	https://datatracker.ietf.org/doc/draft-levine-appsarea-eaiauth/

It would be nice if this could be finished and published, so I have 
something better than an expired draft to point at when people ask me how 
to do DKIM and SPF with their EAI mail.
