The question you're actually trying to answer is unlikely to be "why is this the way that it is" and more likely to be "if I make this change, will I break anything". So just don't worry about it: make your change, open a PR, socialize it as widely as is practical, and if nobody stops you, merge it and move on. In many cases, the original "why" doesn't matter anymore. If it does, having a concrete change to look at and critique helps move the discussion along (and prevents getting trapped in hypotheticals - they can see exactly what you're trying to do if they have a PR in front of them).
