Hmm. You make good points.

Another use of the "hold" (or whatever) concept is in simply creating a sort of stumbling-block in the way of someone approving it without noticing that there's something wrong. I glossed over that somewhat with my last post, though the benefit of a node lacking the "approved by" note was assumed to be based on this means of preventing uncareful approval.

If those who might consider "holding" something would simply post a properly critical response, though, explaining what the problem is, that would probably better serve the PerlMonks community — as you point out. You've altered my perspective. Thanks.
