COMMENT:

I still don't love this - it feels like it is still "reserving" a DNS label,
but -18 text is close enough to having this as  a convention that I'm OK with
it...

Thank you!

Previous DISCUSS position:
[ Edit: Could the format of the _mta-sts to be something like:
"_mta-sts.example.com.  TXT "v=STSv2; id=20180114T070707; label=foo"  ?

This would mean that the policy can be fetched from foo.example.com - the
record *could* specify "label=mta-sts" if it wanted - this allows this to work
without "reserving" a DNS label.  ]

I apologize, this DISCUSS written in a rush.

I'm uncomfortable with the DNS "reservations" happening in this document -- it
basically reserves the (leftmost) DNS labels _mta-sts (as a TXT record) and
mta-sts as a hard-coded name -- I think that this needs to be better documented
/ in the IANA considerations.

I apologize for the lack of detail/lack of actionable content - I couldn't
decide between Deferring and balloting DISCUSS -- I decided on DISCUSS because 
I think I need to think about this, and clearing a DISCUSS is simpler than
having the document stuck for a full cycle.
