In this one particular random case, it happened to be a thing that actually meant something. I am pretty much convinced that that is an outlier at best - most of the time, these questions are just random stuff that is speculative or completely unanswerable other than by rampant theory or the developers, and well, we have close reasons for that sort of stuff.
I could ask a million zillion questions of this type. "Why is Darunia the only bearded Goron?" "Why is Mario red and Luigi green?" "Why is Wario short and round, and Waluigi tall and thin?" and so on.
This strikes me as very similar to a discussion we have had before, about why things got designed the way they did in gameswhy things got designed the way they did in games or gaming industry practicesgaming industry practices. Matthew Read's answer on the first question I linked sums up the point I am trying to make - more often than not, we are not going to be able to answer these sorts of questions, they're not practical, and they're not something that really fits with what we do. If we allow every speculative "why is this thing this way" sort of question, I think we will just end up with a bunch of random trivia-esque questions, which we have kinda made clear are something we don't want to attract.
