The stock security policy for BFG uses ACLs stored on model objects, and
is willing to "acquire" them.  The ACLs represent grant's or denials of
permissions to principals.  The BFG publisher uses the permission
associated with the view to verify access to the view by the current
principals.  All in all, this part is very Zope-like.

Space-suits are only useful if you want to protect specific attributes
or methods of model objects.  BFG has no concept of untrusted code, and
therefore doesn't use them.

You *could* build a BFG-based application which used them (e.g.,
wrapping the root object in a space-suit at the beginning of publishing
traversal);  none of us need or want that.
