It's another idea from Fedora, the theory, IIRC, was that this way, devices would always have the same name, whereas under the method that has been used device names could change on a reboot.
The idea actually came from Dell. It's frequently described as a method to prevent the device name from changing during a reboot, but that was already in place. What biosdevname does is make names *predictable* on Dell systems. It shouldn't be enabled anywhere else.
As you stated, the documented method of turning the feature off is to add biosdevname=0 to the boot configuration (which means rebooting).
