alt Hacker News> Had browser makers supported DANE instead, and had we embraced DNSSEC instead of casting aspersions on it, we wouldn't have needed Let's Encrypt because ownership of a domain name would have already, by that very fact, let you authenticate to anyone.
Had we been using DANE instead of WebPKI, the response to this sort of compromise would be "aw, shucks, someone proved to be untrustworthy and they're in such a critical role in the ecosystem that there's no way to route around this DNS provider being untrustworthy."
> aw, shucks, someone proved to be untrustworthy and they're in such a critical role in the ecosystem
You mean until the DNSsec key rollover completes and they're no longer in that role?
As opposed to what we have now, an indefinite period where crappy non-updated devices will still accept these certs and nothing can be done about it?
The Web PKI works great for browsers. Everything else, not so much.
(To be fair, the crappy devices¹ would probably fail to deal with the periodic DNSsec root key rollovers. But at least that's a fail-closed.)
