The IETF LAMPS group will be discussing a revision of the CAA specification
this evening (morning Singapore time). Hopefully this will codify the
tweaks to CAA we wound up adopting into the Baseline Requirements. However,
there is also a proposal on the table to add a new method of looking up CAA
by using TXT records on an underscored prefix of domain names. That is _
caa.www.example.com, _caa.example.com, etc. Advantage: this makes it easier
for domain owners to express policies different from their hosting provider
/ CDN. Disadvantage: For backwards compatibility reasons, this would double
the number of DNS lookups required per certificate.
It's easy to participate at IETF. There is no membership requirement, and
you can dial in by video even if you've never participated before (there
will be a short prompt to register for the meeting). This working group in
particular would benefit a lot from participation by affected CAs.
If you can't make it to this meeting, you can join the mailing list at
