In https://reactnative.dev/blog/2024/06/25/use-a-framework-to-build-react-native-apps and https://reactnative.dev/blog/2024/08/12/release-0.75#using-frameworks, the React Native team gives the official recommendation to use "a framework" and states:

As of today, the only recommended community framework for React Native is Expo. Folks at Expo have been investing in the React Native ecosystem since the early days of React Native and as of today, we believe the developer experience offered by Expo is best in class.

IMHO it would therefore make sense to provide Expo bindings as part of rescript-react-native.

There are some very very outdated bindings at https://github.com/rescript-bindings/expo.
At CCA, we also have some Expo bindings, but only for the small subset of functionality we are currently using.
