the ipv4 vs ipv6 growth debate

I use a web plugin tool called ipvfoo to track my actual ipv4 vis ipv6 usage. I wish it worked over time. With very few exceptions I am still regularly calling ipv4 addresses in most webpages. Has anyone done a more organized study of say, the top 1 million, and how many still require at least some ipv4 to exist, and those trends over time? -- This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-698136666560...
