   The actual reason for this rule is to prevent the hair dryer from plunging   
   other parts of the home into darkness.  That is a very common occurrence in   
   homes were multiple hair dryers are used at the same time of the day.    
   Limiting a circuit shared with    
   non basin receptacle loads to the single bathroom means that only the one   
   bathroom is affected.     
      
   When the circuit serves multiple basin receptacles then only basin receptacles   
   are affected and no room is darkened by the outage.    
      
   Best practice is to provide the basin receptacle with a dedicated circuit but   
   as that is not necessary to provide electrical safety it is beyond the scope   
   of the NEC.
