Not aero enough?
Having jersey pockets, and useful items in them, doesn't qualify anyone for derisive terms like "pack rat". When doing multi-hour rides, way out on the sticks and dozens of miles from home, an overwhelming majority of cyclists have legitimate uses for things like co2 inflaters, spare tubes, sunscreen, power bars/gels,cell phones, etc.etc. The pockets are also highly useful for stowing away thermal wear that isn't needed after the first hour or so.
There are very practical reasons that most cycling-specific shirts have pockets.
