I haven't created a working build with this yet, but I have some preliminary compression results with a crashing build. Even though the build isn't working, I think these results are what we can expect from a working, compressed JS bundle. The below results are from an optimized production application with a large amount of JavaScript and many native packages installed.

Uncompressed app size: 30.8 MB -> 23.5 MB
Compressed app size: 12.8 MB -> 10.7 MB
main.jsbundle size: 8.3 MB -> 2.6 MB

A functional implementation of this could definitely bring some App Clips below the various uncompressed bundle size thresholds that Apple has set. The original library seems unmaintained and I doubt is compatible with recent React Native versions, so we'd likely want to take inspiration from their approach and integrate this directly into react-native-app-clip (with a config option of course).
