Well it is verification if its on your own site and you're a known person. Because a stranger couldnt use your site. mastodon has something similer .
Nip5 is not verification. It’s just a vanity pronounceable and searchable address aka “nostr address” as coined by nostr:npub18ams6ewn5aj2n3wt2qawzglx9mr4nzksxhvrdc4gzrecw7n5tvjqctp424

No. Too easy to overlook, typo domains, similar sounding domains. It doesn’t verify if you don’t know what the legit domain is. For some people it helps.
