Because the average page is now 3MB in size, and this seems like a good time to pause, check our assumptions, and ask ourselves: Is there any reason to care about page size as a performance metric? And if we don't consider page size a meaningful metric, then what should we care about? They represent trends – that's all.

Nothing in the authors approach actually tests for this, but the program cost metric used to evaluate generated programs encourages it: a program has lower cost for example, if it is free of conditional branches.
