I would think that having an easy call to disable the NX modification would be both
safe and effective. That is, adding a syscall (or whatever) that would let you mark
your heap and/or stack executable while leaving the new default as NX, is "just as
safe" as flagging the executable in the first place.

It clearly wouldn't be safe, and that keeps it from being effective. Like having a great lock and burglar alarm, then putting the key and entry code under the mat. NX is to prevent abuse by BAD PEOPLE and therefore should not have any way to defeat it from within a program.
