OK, there's another thread here with the same subject, albeit the same arguments (opinions)
Resi:
Bedroom; two sp switches, one for the ceiling (wall) luminaire, one for 1/2 switched duplex receptacle. The ceiling (wall) location has a blank cover; the switched 1/2 duplex is OK; THAT IS ACCEPTABLE.
Now; resi bedroom; 1-sp switch; 1 ceiling (wall) luminaire location; OK IF a 'fixture' is installed; NOT Acceptable if a 'blank cover'.
Hallways, kitchens, exterior, bathrooms, laundry area, basements, etc must have a 'fixture' installed for a final.
Hopefully, this is an acceptable answer to this quandry.
