I lack time in my life for a point by point rebuttal.

If you wish to engage the advocates it would help to ask the question
of the relevant mailing lists. There are many, but I don't know them
all, but cc'ing dan york who is big on dane.
To clarify, in cerowrt, dnssec support was one of a dozen technologies
we wanted to prove viable on home routers and e2e, that comcast viewed
it as important enough to fund simon kelly to implement, and it's been
up and working for about 3 years now. We didn't do any real
development of it in cerowrt, we merely tested the results of that
effort and helped file off the rough edges, to make it more generally
deployable. Which it is.
Benefits I see to dnssec end-2-end:
1) The big one, that I personally love, is having a working NXDOMAIN,
where my upstream ISP cannot fill a dns miss with advertising domains.
There are a lot of valuable fallouts from this.
2) It doesn't cost much in terms of cpu or latency
3) A huge percentage of the sites I regularly visit ARE signed.
At least one criticism, now thoroughly eliminated by existence proof,
is that you can't run dnssec on the edge, and the problems that it
causes are mostly invisible - as are the benefits - as it should be.
The author of that post is more than welcome to try it for himself,
day in, day out, as we have.

The debate has gone on 15 years. Alternative proposals need to be viable
enough to merit rollout... which, lacking consensus, would take another 15
Certainly I would like to see DNS replaced with something better, and I
am willing to work towards that goal... but given a choice whether to
deploy dnssec more fully or not, I'd choose deployment.
