Now make it work for mailing lists...

Suppose I run a system that monitors DANE adoption and, as free
service, notifies domain owners when their TLSA records fail to
match their certificate chain.  How will that work?

The IETF "uta" working group is working on a "tlsrpt" standard
to go along along with "smtp-sts", which solicits email reports
from senders when TLS authentication fails.  The messages sent
are a courtesy to the receiving system, who pays for those?

Etc.

"Simple" it ain't.
