Just wanted to add the latest data on DNSSEC [1]. 25 million zones is a drop in the bucket compared to the size of the internet, but it's also not nothing.

| Total number of DS Records | 25,099,952 |
| Validatable DNSKEY record sets | 24,559,043 |
| Total DANE protected SMTP | 4,165,253 |
There's a graph of the growth of signed zones the past 7 years [2].
I get it that DNSSEC doesn’t make a lot of sense for large organizations with complex networks. that have been around for decades.
But if you're self-hosting a website for your personal use or for a small-ish organization and your registrar supports it (most do), there's no reason not to enable DNSSEC. I did it recently using Cloudflare and it was a single checkbox in the settings.
An estimated more than 90% of ICANN's ~1,400 top-level domains are DNSSEC enabled, so that shouldn't be a barrier.
Since most of us don't have a personal IT department at our disposal, for the small guy, DNSSEC prevents cache poisoning attacks, man-in-the-middle attacks and DNS spoofing. There are other ways to mitigate these attacks of course, but I've found DNSSEC to be pretty straightforward.
