Bytes are bytes are bytes, http/2 or no. It's far less intensive to polyfill what features I actually am using than sending down all of jQuery, and that can still be minified, gzipped, cached, delivered via CDN, and cache-controlled and/or placed in the application cache via service workers (where available). But I can understand that it's less about the user experience and more about the developer experience nowadays.
