I don't have a strong opinion, but I suspect that distros actually pay 
attention to each option being set, since they end up having to support 
them all anyway.  As such, they'd generally prefer to explicitly turn 
each thing on or off themselves, and big-switch config options aren't 
all that useful.

But you would have to talk to a distro person to get confirmation ;)
