Angular, React, Vue, etc. are all getting better reducing the bloat. Javascript packaging and tree shaking is also much better. A lot of old compatibility stuff for IE etc. also can be dumped now. JS compilation got faster. The reason we are not seeing any speedup is the code that is not needed: Tracking and advertisements - this stuff seems to fill any size and speed gains.
