As does the fact that it's not a base class in the first place, which is kind of also the point when it comes to offering something like a Warpriest that allows you to play a "paladin of a non LG alignment" from the start.
Well, that takes us back to the question of why we don't have a Holy Warrior base class that accepts alignments other than Lawful Good and Chaotic Evil. (Alternatively, you can turn this on its head and ask why Paladin and Antipaladin aren't Prestige Classes, but the answer to that is obviously historical reasons.)
That is exactly what James is stating that the Warpriest is intended to be.
