As I said on IRC yesterday, there is no reason to expect that simply 
inverting OPTIONS would work. A lot of OPTIONS are not binary, and the 
defaults are chose to work together, often in harmony with the 
dependencies that they trigger.

Put another way, it does not logically follow that if "A, B, and !C" 
works that "!A, !B, and C" would also work.
