When I used a small local ISP that did not support ipv6 before switching to AT&T fiber¹ I tried to set this up, but they demand an email on a non-gmail domain, and I wasn't going to pay to set that up nor was I going to use my work email. It's a bad assumption that any non-malicious user cares enough about websites to have one.
1: I'd prefer to have stayed with the local ISP despite the lack of ipv6, but they wanted $8,000 to bring fiber to my new place and that was not worth it with at&t fiber being present.
