Another way of looking at this: "What will we do if the price of bitcoin hits $1,000,000?" That would be the point at which a satoshi, the smallest possible unit of bitcoin or 0.00000001 bitcoins, would be worth a penny. And so there would be a reasonable argument to increase the maximum subdivision level. And so that could and likely would happen with minimal fanfare - certainly less than the recent split received. With a theoretically infinitely divisible currency the amount of currency in circulation is not really relevant. And this issue, as small as it is, only becomes one at price points that will not be reached anytime in the foreseeable future, if ever.
