Claude once objected to implementing HTTP/2 for jpm, but the author insisted; measurements showed HTTP/2 was about 17% faster on home connections, but flat or worse on GitHub runners, with cold-start nuxt installs up to 2 times slower, 8% to 15% more CPU consumed on large tarballs, and a 60KB increase in binary size, so the 3671 lines of HTTP/2 code were ultimately deleted.
