I use it extensively in my OSS work (https://github.com/mickael-kerjean/filestash) mostly around:

1. creating plugins that get executed in the browser to render files like Parquet, PSD, TIFF, SQLite, EPS, ZIP, TGZ, GIS related files and many more, where C libraries are almost always the reference implementations. There are almost a hundred supported file formats, most of which are supported through WASM

2. creating plugins that get executed in the server to generate your own endpoint or middleware while being sure you can't start exfiltrating data (which can be other people's files, and other sensitive stuff)

3. in the workflow engine to enable people to run their own sandboxed scripts without giving those a blank check to go crazy
