Aren't we a bit unfair comparing the failures of past PKI CA infra with
a still upcoming DNSSEC infra?

My understanding is that DNSSEC is facing similar issues that PKI CA had
many years ago regarding root keys ownership.  Only time will say
whether deployed DNSSEC will have market acceptance and end-user
confidence thereof.

I agree. So, DNSSEC provides me both a secure link and greater
confidence that I am speaking to the correct domain name

fwiw I have always envisioned the significant impact of DNSSEC was to
provide a "trusted" method for tying the public key used in TLS to the
domain name bypassing the "leaky" CA infrastructure.
