Examples for why this would be helpful

Problems like uuidjs/uuid#392 are another good example of why it would be really helpful to have a CSPRNG baked into the JavaScript language (as @broofa noticed in uuidjs/uuid#392 (comment)).

And there are more: Right now we are struggling to make a CSPRNG available for React Native environments, see uuidjs/uuid#375

• For bare react native you can use react-native-get-random-values as a polyfill
• However that doesn't work in debug mode Use Math.random when debugger is attached LinusU/react-native-get-random-values#8 😢
• And it also doesn't work in expo: Compatibility with uuid 7.x, nanoid, and others expo/expo#7209 😿
• Expo does have a CSPRNG, but it's async, so it's incompatible with the uuid APIs that are all sync 😭

Interestingly, the users of these platforms have unknowingly been using the Math.random()-based fallback for uuid generation for years. It only became apparent when we removed that default fallback from the uuid library.
