fair point, perhaps partially compensated through tls-protection for recursive dns. don't know how common that is.
i wonder whether there is any move by e.g. linux distro's towards including a dnssec-verifying resolver by default. whether they think it's not worth the trouble, or what the inflection point will be. i usually install unbound on new machines. i believe openbsd comes with unbound by default? assuming that's with dnssec-validation enabled.
i used to dislike the unhelpful generic error messages for dnssec-related problems (servfail). perhaps that was holding adoption back. but extended dns errors (ede) seem to solve that, though i don't know how commonly the detailed errors make it up the stack in old software.
Yes, but this isn't a replacement for the WebPKI because it would allow the recursive to impersonate any site, which is obviously unacceptable.

A year or so ago we took some measurements of DNSSEC success rates with Firefox on known-good domains that we controlled and the results were very bad. I don't have the data to hand right at the moment, but requiring DNSSEC validation would have produced unacceptably high failure rates.
