why does holo require rooting for wireless ADB?

[plaurits]

Hi! I see this note under features: NEW: Wireless ADB support has been added! You can now natively connect to your device wirelessly, provided you've enabled wireless ADB on your device using an app or a custom ROM. Note though, this requires your device to be rooted. But wireless adb app works fine without routing, so why does holo require this. Holo works fine for me using USB.
