If you improve parsed/scanned speed of html in Chromium by say 1%, that doesn't sound impressive. Then you consider 3 billion people use chrome (or Chromium derived browsers) multiply that out by how much html gets parsed/scanned a day by those users and then consider the energy costs - it quite quickly gets to a massive number (and that's just actual users, Chromium is also the core of Electron and a alot of other tooling) Simply put at Google's scale, tiny incremental gains compound to a massive species wide saving. At scale everything matters :).
