Simply, the "common sense" is lost when the option is not available to us in the 3DS when "common sense" dictated it could have easily been. Therefore I'm not sure of anything, and that's the safest vantage point for an opinion about this topic. Simple enough, I'd be glad to know as well in a more accurate less "on a hunch" manner. Because my assumption left me a bit high and dry already once.
And frankly, nothing about your response was clear that you understood... it was sarcastic and assuming. Even if you end up being correct, it was not a helpful stance you've taken. "Common sense" and smug smilies are borderline rude in this context, with little to no actual detail or helpful information considering what facts we actually have to work with currently, which seem to dictate the opposite anyway.
