good link.  SimonP, I get where you're coming from, now.  Yes, the "unreferenced" tag is more onerous than what you're doing.  But what you're doing comes across a little heavy-handed, as though your suggestion is a veiled threat to follow up with officious intervention.  How about instead handing people a link to a page where you explain the reason you're doing what you're doing (the history of it)? Then they'll be able to decide if it's appropriate to the level of their article.
