This is true with the default Zope "storage" FileStorage.  It's not
"dumb", because it's the feature that makes undo and versioning work.
Other storages like dbmStorage and Ty Sarna's BerkeleyStorage don't work
like this, and they might be more suitable for you.  Of course those
storages don't do undo or versioning.
