I don't think we should suggest any particular set of ACLs.
We should just detail to administrators how ACLs may be used
to implement various access control policies.  What policy
the administrator should choose is their choice (a choice
which is dependent on numerous factors).

The existing examples demonstrate how to implement some basic
policies.  These examples are intended to aid the reader in
understanding the syntax and semantics of ACLs.  They are
not intended to suggest appropriateness of these policies for
any particular purpose.  (Maybe this should be clarified.)

Way too complicated for educational purposes... and too dependent
on non-standard schema elements (for non-standard applications).
(This is not to say that more complex examples wouldn't be useful
here, but the documentation would have build up to them.)
