No, it's not a »minor design detail«, at least not regarding
what has been the topic of the discussion here – you can always
provide a simple wrapper function in the proposed design and call
it »stateless« as well (in fact, an implementation has already
been posted, IIRC).
The point is that the ability to execute a hashing operation
block by block is necessary, and that this operation is not
analogous to reduce() because it potentially needs internal state.
