Chrome apparently tested zstd out, and it's an improvement over Chrome's forked and optimized zlib on x64, but slower on ARM/Android. https://bugs.chromium.org/p/chromium/issues/detail?id=912902...

Few (or none?) of Chrome's fairly dramatic improvements to zlib have been upstreamed. https://github.com/madler/zlib/issues/346

Edit: Also, if browsers do adopt zstd, it's likely you'll end up with the same situation where they fork their own implementation of zstd. Upstreaming requires signing Facebook's CLA, which has patent clauses that don't work for most.
