Yeah, but I believe for most users the only reasonable default for
things you get from the key servers is don't trust without additional
evidence.
For most users for most domains, I believe a reasonable default for this
dane record is trust if you otherwise would have sent plaintext mail.

It's all in the probabilities.
I'm making a judgment based on how I've seen PGP used over the last 20
years or so.
It seems like other people I believe to have used PGP a lot are making
the same judgment on this proposal.
Yes, that's appeal to authority.
The only thing I can think to do beyond this is consider the sorts of
examples you're bringing up.
You think they argue that the key servers and this proposal are the
same.
I think they are interesting experiments that validate the utility of
this trust model in interesting cases.

There we disagree.
I think implicit endorcement from the domain is valuable even if I don't
know much about the domain.
