I know some people don't care at all, but the internet was made to be addressable. IPv6 is the only shot we have to go back to that.

It’s not implemented in the Linux kernel, but the latency penalty you’re describing is part of the “Happy Eyeballs” algorithm: https://en.wikipedia.org/wiki/Happy_Eyeballs
As sad as it makes me to admit, I don't think IPv6 is ever going to happen without government intervention. Adoption is flat at under 50% over the past year. IPv6 doesn't benefit big tech. SNI routing and NAT work pretty well for centralized platforms. AWS will gladly rent us IPv4 addresses until the end of time.
Why, so you can inflict some personal pain on people without IPv6 access?
Making IPv4 intentionally laggy would break orgs that depend on ancient gear or SaaS with hardwired v4, for a purist's thrill and outages for users.

That sounds so bad, it probably will be a windows feature.
Please no. I used to have a Dutch ISP a few months ago that did not support IPv6 yet. (Odido. Same ISP that leaked my data in a big hack.)
This reminds me of the ways the governments screw over people to force them to do things they don’t want to.
- I don't want my interfaces to have multiple IP addresses
- I don't want my devices to have public, discoverable IPs
- I like NAT and it works fine
- I don't want to use dynamic DNS just so I have set up a single home server without my ISP rotating my /64 for no reason (and no SLAAC is not an answer because I don't want multiple addresses per interface)
- I don't need an entire /48 for my home network
IPv6 won't help the internet "be addressable." Almost everyone is moving towards centralized services, and almost no one is running home servers. IPv4 is not what is holding this back.
