small Bathroom exception 'farthest wall' NEC 406.9(C)

I was curious what made them add the phrase 'farthest wall' in the exception for the location installation of a receptacle in bathrooms 2023 NEC 406.9(C) execption #2. Reason I ask is because I have seen too many old houses with small bathrooms and the 'farthest wall' is a wall with the entry door and not by the sink and vanity. So if someone was to follow the technical 'letter' of the code it would be interpreted as a code violation by some.

In reality, most installers ignore it anyways, as it is safer to have a 20amp receptacle right by the sink and vanity that is used for shaving etc.. like normal than to have extension cords or a light fixture receptacle that home owners do themselves.

What is the reason for the 'farthest wall' ? Shouldn't that phrase be removed and just keep the rest of the wording?
 
Going from memory even with the farthest wall nonsense isn't the receptacle still required within 3' of the edge of the basin?
