Hoi, Wil it work using the #babel templates?
No, because that would be inconsistent with the fallback that is applied when using Lua or {{#property}} in wikitext. The fallback is based on the fallback that is defined by MediaWiki for the interface labnguages.
In wikitext, we cannot use the Babel templates, because that would break caching. The rendering can depend on a few user specific settings, but caching a rendered version of every page for every possible combination of babel templates is not feasible.
We could in theory use a different fallback mechanism on Special:AboutTopic, but that would be quite confusing - why does it look differently in articles? Also, when talking to others about the output of Special:AboutTopic, this might get confusing: if someone complains that e.g. some label they see there is wrong, and you go to the page but what you see is different, it becomes hard to discuss the issue. There would be no way to link to the page as you see it. Everyone would potentially see different output.
