Nothing really, I added the list since it seemed that explicitly setting 
the directories would allow people to explicitly say what they'd like to 
allow to be disabled.

Don't have an opinion either way. Probably should just get a build 
person to weigh in here with what they want. I'm happy to adjust the 
patch if they want that way and test it. Just need someone to say 
something. :)
