I very much like the idea of this draft, given that I use multiple DNS hosting providers who all have their own unique (and proprietary) way of doing "CNAME flattening at the apex". I think the reality of today's user experience with domain names is that we are increasingly dropping the "www" or any other kind of second-level domain. So we want to talk about our sites as "example.com<http://example.com>" ... but as the publisher we want to use CDNs, load balancers and other systems that need us to use a CNAME. A standardized way of doing this would be helpful.

One comment...

(Incidentally, I'm working on a somewhat more ambitious ANAME draft with
Peter van Dijk and Anthony Eden, who has kindly agreed to merge his efforts
with ours. I expect to post it in a few days, stay tuned.)

... I think it would be helpful for the new draft to have a few examples of what the RR would look like in a zone file.  (This was the one component I found missing from Anthony's ALIAS draft.)

Thanks for doing this,
Dan
