On: "1) Remove the "_" from DNS records to be consistent with A/AAAA
records used with the HTTPS retrieval, and make this a bit less confusing
for deployments.  We did this for both MTA-STS and TLSRPT."

Having just tried to implement this, I bumped into a problem that I can't
use a CNAME to an ELB for the https bit and set the TXT record in the same
zone because it has the same DNS name and CNAME is special.

Have I missed something, or does this mean it's not possible to use CNAMEs
for hosting the policy document? If so, I think that's going to be a pretty
painful blocker for a lot of people.

Cheers,
David
