It would be wonderful to have brotli in Edge! Eric's work at http://textslashplain.com/2015/09/10/brotli/ shows that a variety of internet-related systems can benefit from it. Firefox supports brotli since September 2015, and net-stack level brotli-integration was added to Chromium code a few days ago. Also, http://caniuse.com/#search=woff2 is running on top of brotli, possibly partially covering the binary size increase that a new codec like this gives.
