Not sure about the cost delay thing. Delays are disabled by default for manually issued VACUUM, so have doubts that that's useful.
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.
