I'm not quite sure if I understand you correctly. The handbook talking 
about *options* that default to on, not variables. It means if you have 
a super-duper feature that is turned ON by default then you may have a 
WITHOUT_SUPERDUPER switch that turns it OFF ... and the other way 
around: there is a useless feature that might be turned OFF by default 
then you probably have a WITH_USELESSFEATURE switch that turns it ON. :-)
