I see your point and agree that it's unnecessary to have both a tweak to criteria and janitorial checkoff. And if unreaping is handed down to the janitors, that will help to eliminate the problem.

I am mostly concerned with those times when you go to the fridge to grab a can of coke and find that by the time you return, someone has considered a node for reaping, and it got its required votes and was reaped before anyone with a little more seasoned judgement has time to step back and say "whoah, what's going on here?" I don't think anyone would argue with the assertion that there have been some things reaped that probably shouldn't have been. More demanding criteria, and the ability to unreap will solve this problem.
