The new wording in 210.8 NEC 2018 states that when determining distance for GFCI's it is "would follow without ... passing through a door. My first thought is that if the receptacle has to pass through a door, then a GFCI isn't required on the other side of the door. But I think I have read here where it is believed to be required. Can we discuss the reasoning? I can see where one might state, a cabinet door isn't a "door" in this case, for example.
