I agree there are just a bunch of trade offs, and this shows you can’t please everyone. If you ship large bundles of polyfills people are sad they get some slow JavaScript, and if you give them fallback html and JavaScript that renders quick and supports their feature set, they are sad they didn’t get the same feature set as chrome latest. You have to minimize the fallback sadness as well as keep pushing better and better cutting edge experiences. This demanding environment is one thing I do like about the job even if it makes me feel constantly unqualified and doomed to fail :D Speaking personally from my time before working at Google, the second network request is definitely the worse of the two options if you can’t do anything until it completes for most people- the round trip time kills you in the median US case I am familiar with. At Apple for my small project we didn’t have these constraints so we just shipped a giant JavaScript bundle with feature detection and browser-side re-rendering that worked alright.
