With so many multifunction SOC embedded controllers out there it's possible some one just didn't cut the lines to the radio built into the board that was selected for other reasons. Would not surprise me to see a lot of control boards that expected firmware or dip switches to disable unneeded functionality versus having a different line for similar boards if they weren't being made to a specific end customer anyway.
