I know you know this, but in the interest of the brand name article I just read, I feel obligated to point out the following:
Golarion is a Pathfinder setting!
PAIZO was creating D&D modules for it ..albeit SRD...before Pathfinder. Maybe that is the reasoning?
That said, not something I would consider official either. If that was the case, you would have to take into account everything ever introduced via a crappy old D20 glut module.
