For web serving it's possible to have IPv6-only server accessible to anyone. Just use Cloudflare. I'm not sure it's documented but I started using IPv6-only origin server behind Cloudflare and it seems to work OK for people connecting both IPv4 and IPv6. The client IP is in CF-Connecting-IP, even for IPv4 connections. For me it just works.
