I really like Intercooler.js's ideas for starters.
It may arguably improve your site's experience on a desktop/laptop or even touchscreen phone, but it worsens your experience on, say, a "smart" TV or voice assistant even more so. This promise of universal accessibility was a big selling point for the Web early-on.
For people who care about, support, or build Free, Libre, and Open Source Software (FLOSS).
