My 'issue', which is wildly off topic from the original post, is that Twitter Lite is hailed as the epitome of Progressive Web Apps by both Google and Twitter. Google helped Twitter build it. They claim that it's a faster site because of PWA, but the site is slower where all the PWA technologies would help out. Where there are speed improvements, it's got nothing to do with service workers.
