Examples for why this would be helpful

Problems like https://github.com/uuidjs/uuid/issues/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 https://github.com/uuidjs/uuid/issues/392#issuecomment-593622182).

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

• For bare react native you can use react-native-get-random-values as a polyfill
• However that doesn't work in debug mode https://github.com/LinusU/react-native-get-random-values/pull/8 😢
• And it also doesn't work in expo: https://github.com/expo/expo/issues/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.
