(For myself, I take care on my site in the few places I ever use JavaScript, and also even vary my content in feeds where it depends on JavaScript or site styles, which I’ve never noticed anyone else do. make-and-git-diff-test-harness and dark-theme-implementation are slugs of two sample articles that both vary by JavaScript and feed, I won’t drop links.)
