Presumably the dependency tree would look something like: persistent < BTrees < ZODB < ZEO The persistent dependency is definitely less to swallow than the whole ZODB for a potential user of the BTrees package, but its still a complication and there's no urgent reason to make the change now. Smaller, iterative changes usually win.
