Right, but you still have the option to enable them if you don't want to
swamp your IO system. That's why CIC obeys it too. If I was running a
consistency check on a production system I'd certainly want the option
to throttle it. Without that option, I don't see running this on
production systems as being an option. If that's not a goal then fine,
but if it is a goal I think it needs to be there.
Isn't it just a few extra lines of code to support it?
