This is a (deprecated) alternative for "security.declareObjectPrivate()".

Yes, many methods of "OFS.SimpleItem.SimpleItem" and its base
classes rely on its "setDefaultAccess('allow')".
If you change this to "deny", you have to provide the
explicit security declarations.

"setDefaultAccess('deny')" had a bug in some earlier Zope versions.
With the exception of this fix, nothing changed here for a long
time. You can still use the Zope Developper Guide...

As what?
The "default access" also controls access to attributes of
simple type (strings, tuples, dicts, ...) which cannot have
their own security declarations.
If you do not access such attributes directly and
you provide security declarations for all methods you use,
then you can keep "defaultAccess == 'deny'".
