The "so" is that once you're talking about APF authorized programs 
MVS security concerns are no longer on the table - the door is
open.  The technique used at that point - manual response to a 
security prompt, automated response to a security prompt, access 
to the dataset without going through a security check, etc. doesn't
really matter - technical details.  

If a shop has lax controls over authorized libraries then they indeed 
have a security problem, but it's not a "mainframe" problem;  it's a
management problem.
