Seconded this. I wanted to have a way to stream packets of some really repetitive data to javascript in the browser, and zstd-compressed json with preset dictionary really would have been the best way. Ran into a lot of problems getting zstd ports in web browser working nicely. Ended up just using a handcrafted binary format.
