A new ATSIN has been issued:-

Put simply, if you are flying private VFR in a SEP within a NFZ ATC should offer you traffic services. An encouraging step.
Still no confirmation on whether the NFZ applies as much to <3000' light piston singles as it does to turbines in the flight levels however...
Also I hear that people flying within NFZs might be MOR'd. Another pressing reason why this matter needs to be clarified ASAP!
