The library has been kept small because its current interface will serve most purposes. If and when a genuine need arises for more functionality, it can be implemented.
One should always start with a generic algorithm that takes two iterators (or more) as input. Then use Boost.Range to build handier versions on top of the iterator based algorithm. Please notice that once the range version of the algorithm is done, it makes sense not to expose the iterator version in the public interface.
Even though we speak of incrementable iterators, it would not make much sense for ranges; for example, we cannot determine the size and emptiness of a range since we cannot even compare its iterators.
Note also that incrementable iterators are derived from output iterators and so there exist no output range.
