The problem is not that this particular article has a chance for deletion (and it does, if people don't stay on top of it). The problem is that these processes force repeated active defense and maintenance by people who don't want to see useful content deleted, whereas a momentary lapse in vigilance produces a "default" answer of "a few of people think it ought to be deleted and nobody has chimed in in defense with citations for chapter and verse of Wikipedia policies, so let's delete it".

If you'll forgive a political analogy (which seems appropriate given Wikipedia involves politics): What do Wikipedia, governments, and very young children have in common? You have to watch all of them carefully so they don't do something painfully wrong and injure themselves or others, they have a lot more energy than you do, they don't have or use much common sense, and they keep persisting because they can get away with things if you get tired and look away briefly.

And yes, I do know what I'm talking about; I've participated in Wikipedia for years, dealt with several of its policies, and watched its internal workings extensively with both fascination and disgust.
