1984 was about right IMO, when the last legit changes came about (besides separate N/G of course).
Personally if I had my way:
Crow foot receptacles or the IEC-60906-1. GU sockets. Sleeved or guarded prongs, but no TR. No AFCIs, or GFCIs indoors. Circuit sized to disconnection time not exceeding 0.4 seconds in kitchens, bathrooms, basements, outdoors, ect 0.8 seconds everywhere else. All metal connected to a CPC where not part of a double insulated assembly, no exceptions. No minimum service disconnect size. Service entrance sized based off of 50% of the load calcs. 15 amp circuits where 20 is required now. 2 wire switch legs. Lax stapling after first staple above box. Receptacles every 5 feet, but not required where cords hanging from counters can be pulled by kids. Discretion left to the electrician on how many circuits, division, design, ect.
