I don't know how you'd get it into the NEC...
But, single family homes really ought to have at least one GFCI outlet sited for festive lighting -- switched either manually from a floor walking height -- or via a clocked switch from a dry location -- as in heated, conditioned spaces.
This set up is needed for harsh weather -- and for the elderly.
Crazy risks are taken just to fire up light strings -- both electrocution and ice falls.
This kind of set up is a common as dust in my commercial prints. I can't recall of a shell contract that didn't have a provision for festive lighting.
It also wouldn't hurt if someone came out with light strings that were integrated with clasps that -- once mounted -- could stay on the building year-round -- and yet accept the light strings when lifted by a pole-grip -- all to get the public off of ladders in the dead of winter.
Every year the ERs of North America are stuffed with ladder-fall victims -- who were trying to place and remove Christmas lighting strings -- mounted via crude finishing nails tacked all along the exterior in the tackiest manner.
