Well of course, in the "Other" field on the AAN, you'd put the denial reason as "Covered borrower status", not cite your own failings as the reason.
Terrible idea, in my opinion, and the reason that many shops that don't expect to have many of these loans ever come up are still scrambling to have to figure it out in time. I'll be surprised if we have one or two a year (though the hybrid loan uncertainty could change that opinion), and I'm hopeful that the training required of staff will be "If you see this flag on the credit report, stop, drop, and roll over to this set of procedures that will step by step tell you what to do". We'll see if the lending arm ever sorts out those procedures.
