There are also JS maps which allow you to download the obfuscated blob but still view more or less what is the original code; used for debugging React/JSX code, for example.

Outside of OSS, these are not frequently shared with the public. Is Honey's?

Yes, if set to maximum minimization. They might retain the original names to help with debugging, possibly.

Chrome extensions allow minimisation, including destroying the original names. I'm curious how they review the extensions to be honest as they don't ask you to provide the source code or the source map.
