Current statistics are that a bit over 70% of websites are IPv4 only. A bit under 30% allow IPv6. IPv6 only websites are a rounding error.

Therefore if I'm on an IPv6 phone, odds are very good that my traffic winds up going over IPv4 internet at some point.

We're 30 years into the transition. We are still decades away from it being viable for servers to run IPv6 first. You pretty much have to do IPv4 on a server. IPv6 is an afterthought.

Just put Cloudflare in front of it. You don’t need to use IPv4 on servers AT ALL. Only on the edge. You can easily run IPv6-only internally. It’s definitely not an afterthought for any new deployments. In fact there’s even a US gov’t mandate to go IPv6-first.

It’s the eyeballs that need IPv4. It’s a complete non-issue for servers.

Why do I have to get some third party involved??

Listen, you can be assured that the geek in me wants to master IPv6 and run it on my home network and feel clever because I figured it out, but there's another side of me that wants my networking stuff to just work!

You have a point. But you still need DNS to an IPv4 address. And the fact that about 70% of websites are IPv4 only means that if you're setting up a new website, odds are good that you won't do IPv6 in the first pass.
