Yes, a peer of mine recently wanted such an option to disable individual 
passes in order to 1) narrow in on a bug in one of them that affected 
stack back tracing, and 2) provide a workaround for the bug.  He didn't 
pursue modifying code to remove the passes one at a time and thus the 
bug remains hidden.
