The problem is, the required changes in our attitudes is precisely what's missing in how we do things now. We already have the process in place, but we (meaning /me) are sometimes too lenient about what we'll approve. We could withhold approval, or we could consider the node without it.

You could be right about the testing - it may drive people away, who simply don't want to be bothered with an annoying hurdle. I don't have any great fondness for the idea. It was just a thought, and from what you say, it doesn't look like a particularly good one.
