> The message isn't even about load time performance, it's about runtime optimizations. There tends to be a fetishization of load time and time to paint performance on web, and gross neglect of run time performance and user experience once the web app loads. Some devs seem to forget someone is going to want to actually interact with this thing once it loads and 5fps needlessly jittery, janky UI (among other things) has contributed to the death of mobile web altogether in favor of native apps.
