The "sibling inheritance" you are describing is Zope's "acquisition".
Folders derive from Acquisition.Implicit, which means they are willing
to acquire any "non-private" name from their parents.

To prevent this behavior, place SubA with a Folder-like object which
derives instead from Acquisition.Explicit.
