That's the thing, though. They really aren't demanding, requiring, or forcing you to play in a certain way. They're just saying, if you do want to play in some other way, then you'll need to tweak some of the other rules.
And yes, it's a major cop out that they don't tell anyone how to tweak those rules to achieve any other playstyle; but that's still not the same thing as mechanically requiring a specific playstyle, with the intent that every rule be followed to the letter (as with 4E, and it's famous "everything is core" policy, for example).
