"a [...] over-engineered feature that is utterly crap"
I'm not usually trying to police this kind of thing, but is there a way you could have phrased this without discrediting the work of a lot of people whose goal is to help others? I'm sure you'd get both a little bit hurt inside and defensive when someone in your team calls your code "utterly crap."
That said, I'm very sure they will be happy to hear about your feedback.
As someone who works on the team that built this feature, thank you for saying this.
As for feedback, we've had 4 years of it and welcome more.

If the Wikimedia Foundation's goal was to help people, their time and money would be much better spent hiring professional / full-time editors to QC their content. Features like this hovering preview are peripheral to their goal of providing quality content that can also be updated by the general public
