What I read is that the current adiz requirements would be made
permanent. Where does it deviate from that?

AOPA says it will be a restricted area:

AOPA will oppose an FAA proposal scheduled for release tomorrow
that would codify flight restrictions in the Washington, D.C.,
metropolitan area. The restricted area would replace the current
air defense identification zone (ADIZ). It would receive a
brand-new designation, "National Defense Airspace," and cover
nearly 2,000 square miles around Washington, D.C., extending to an
altitude of 18,000 feet.
