That rules applies at a lower level. It removes the need to have
special-case handling for the many low-level objects that should never
be web-accessible.

Almost all zope-manageable classes (and certainly Folders, that Dieter
mentioned) use the old rule. This happens because they derive from
SimpleItem.Item, which has __allow_access_to_unprotected_subobjects__.
