Paraphrasing Einstein, I think the hierarchy should be as flat
as possible, but no flatter.  For example, I see no reason to
materialise in the hierarchy the separation between persistent
and mutable data structures.  The should be a documentation
issue.  However, and as you noted, there are cases where some
hierarchisation may remove namespace clutter and allow for
better code reuse.
