Things like you are describing are not always designed from the ground up the way you see them in the end. It's quite probable it built up over time starting with just a few controls ending in many. It's easy in retrospect to see this error but it's been built and shipped and probably lower priority for a company of that size. This is a pretty common issue for large companies or projects with many people aka design by committee.
