My experience with the Xcode build-settings editor is that when Apple wants to obsolete a key, it drops the plain-text equivalent and confronts you with the literal key. By that precedent, these keys appear to be in some sense alive.

Google is of no help — it refers back to the Apple documents and to some guy asking in 2004 the same question I'm asking now. Searching the Apple developer forums turns up nothing.

(Which sounds like a thundering security hole.) But that memory is so wispy that I may just be making it up.
