That's not how I read the policy / guideline to which you gave us a link. However, wiki policies / guidelines are not my specialist subject. When I have taken time to try and figure them out I have frequently been mightily impressed by the level of internal contradictions in many of them.
As far as your suggestion is concerned, therefore, it's largely a question of intuition and common sense. Yours.
As far as superscripts are concerned, when I use them I find they tend to get corrected (aka reversed) by well intentioned people who (presumably) think superscripts look funny (which on little screens and portable telephones they probably do) and have (presumably) found a wiki policy / guideline to support them in the opinion they thought of in the first place
As far as my own reaction is concerned (1) this entry has a lot of red links. Uncomfortably many if you don't like the colo(u)r red. But (2) several of them are likely to turn blue in the foreseeable future as people are moved to translate them. That's the point of the little language icon linking to a perfectly adequate (in .... many cases) wiki entry which is in the "wrong" language. Problem is, I don't have any way of knowing which of the red links is likely to turn blue in the foreseeable future when people have moved to start a translation into English. Different people have different areas of interest. And, in fairness, some of the non-English wiki language entries linked here are ... better than others!
