I personally would like to have the raw interface or both the raw and simple interface available. Some package maintainer (in whatever language) would assume everyone has the same requirement as them and make only the 'ultra simplified interface' available. And it's generally a big headache if it didn't met your requirement. So you end up copy paste and modify or forking the whole project. But that could totally be avoided if you just export both of them instead of hard-locked the interface. People don't really want to fork the god-damn project just to change the two character you hard-coded. Even marking them unstable and making it unsupported would be far better than locking it down completely.
