After looking at the bug fix, I've concluded that allowing these new 
config options is the right thing to do, even though it's technically a 
new feature. There is no good alternative other than leaving the bug 
unfixed until Newton. Doug's concerns notwithstanding, I don't feel the 
risk added by this feature is any more than some of the other bug fixes 
we're allowing in.

This FFE is granted.
