Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

It might have helped in this narrow instance, but it doesn't solve the problem in general, because BGP hijacks IP addresses, not DNS addresses (although you can hijack IP addresses in order to hijack DNS addresses). And that narrow save comes with big trade-offs elsewhere.
But hijacking BGP is meaningless if everything in the future is TLS+DNSSEC authenticated, yes?
I don't need to hijack your domain name if I can just hijack your IP address. And having done that I can get CAs to give me DV-validated certs for it.
But the IP address doesn't matter if the DNS isn't pointing to it, right? Then you can't get a cert for the domain if the DNS isn't authenticated.
There are essentially 2 layers of DNS on the modern IPv4 internet. BGP is DNS for IP subnets.
