> This feature is wholly new to Haskell (and to programming, more generally), and we will learn more from experience. But we cannot gain the experience without incorporating and releasing the feature. We thus label it as subject to change. Changes will be incorporated into this document before they are released.
> These changes might continue (without prior debate here) even after a release, but all changes will be made in consultation with the GHC developer team, via debate at GitLab
