This function, if implemented, would definitely be cleaner than using the workaround of a separate data-loader module.

@Nihiltres "full width" isn't actually the same as flow breaking. There are a number of images in our articles which are in what I'll call "extreme landscape" orientation --- very wide and not very tall.

If I understand it correctly, the infobox "does not show" a link to various templates ([[Vorlage:Infobox Hochschule/Mitarbeiter fehlt]], [[Vorlage:Infobox Hochschule/Logo fehlt]]), possibly as a way to track the pages with missing data through WhatLinksHere.

What's unsound about using an edit filter? It's the surest way to prevent other moves to the namespace from happening. That client-side fix could be accidentally or maliciously bypassed simply by disabling JavaScript. That said, it seems like a good idea to make the option invisible as well as using a filter.

There might be a use-case for moving stuff to/from the Topic namespace, but until one's established, and pages can be moved back, I agree it should be disallowed. I've set up filter 658 to help prevent it from happening again in the meantime.
