I saw this over on comp.risks... Apparently there is a proposal to
have the FAA stop publishing charts for "security reasons".

Not FAA, NGA, formerly known as the Defense Mapping Agency (and then
NIMA: Not into mapping anymore). NIMA produces a variety of aviation
charts: WAC, JNC, ONC, etc.. for the entire world. Most civil pilots
don't see any of these other than WAC's.
