Removing propTypes in production build?

What do you think about removing the propTypes in the production build to reduce the bundle size using babel-plugin-transform-react-remove-prop-types?

I’ve already prepared a fork, so if you think it is a good idea, I can submit a pull request.

To be honest I feel like it might have been better to actually enforce stripping propTypes in user code. We might make a breaking change like this in the future.

We definitely don’t recommend relying on propTypes for any runtime behavior. It’s not at all obvious, and can lead to confusing times for anyone working on the project in the future.

I think there are some valid use cases for accessing it, like

DangerButton.propTypes = {
  ...Button.propTypes,
  somethingElse: ...
}
