Scott, many of us see that as opinion only, often repeated here though scientific research is never cited to substantiate it. It ignores the large areas of the world that has long days all winter long, as if the chicken has been "designed" to suit only the poster's own specific geographic area and the rest of the world does not exist. 
If one wants to look to Ma Nature for the "natural" break from laying that she designed into chickens, I would think that we need only to look at the moult for that. Any additional "rest" that a chicken may get due to short winter days is only a matter of where it lives. 
As you probably can tell, adding light is a subject of which there are many opinions. You will have to determine what you are comfortable with. I would rely more on scientific data than on those whose whole idea of what is "natural" is based only on what they observe in their northern latitudes, those who will present their ideas of chicken reproductive physiology without offering scientific substantiation or those who will assume some perceived moral high-ground because they don't use artificial light in the winter while those of us that do are "hard-up" for a few eggs or just as bad as factory farms. (Yes, I've heard that from supposed "experts" here and elsewhere.)
As you  probably guess, I "extend" my chickens' day for several hours. Is it necessary? No. Does it increase their productivity over the winter? Yes. Is that a bad thing? No. At least no one here is offering any scientific data to prove that it is.
