Yes, WW works on the Points system or a list of Core foods, and LAWL works on exchanges, and Body For Life works on mini-meals, and SBD works on a specific food list, and so on and so forth...but it all boils down to the fact that they are pretty much ALL reduced calorie diets. It is calories in vs. calories out...it is just the fact that each plan has its own unique system for reducing the calories.
Points is just a shorthand way of counting them...LAWL limits calories by allowing you certain amounts of each food per day...SBD reduces calories by not allowing you to eat lots of refined carbs and sugars, therefore reducing your cravings for them, and naturally eating less calories is the result.
It all boils down to the fact that 99% of weight loss plans have you eating less calories to lose weight. So, with that in mind, this is why I think it is redundant.
Yes, if you go into the WW section and find a recipe, it might have the Points value listed...but, if we listed a recipe here, we would STILL have to figure up the calories (and other macronutrients) for ourselves, because of the slight differences between product brands.
If two of us here eat toast with peanut butter and banana slices for breakfast-we could very well end up with different calorie and fat counts for those items, depending on what brand and type of bread was used, and what brand and type of peanut butter. The calorie counts are not going to be the same across the board.
We all know that one brand of light bread is 40 calories a slice, and another brand is 60. One variety of Prego sauce is 80 calories a serving, and another is 100 calories a serving. Unless the recipes were written out exactly to the letter, we would still have to do SOME figuring on our own.
I used to moderate over in the LAWL section a couple of years ago, and dealing with the recipes and Stickys and keeping the chatter out of the recipe threads isn't quite as easy as you might think.

It ends up being done in two ways-either the recipe threads are general threads, and I have to go in every day and delete the "chatter" posts to keep things organized (I made this last night...and it was GOOD!) or, I have to make the recipe threads as locked sticky threads, which means you would pm the recipes to me...and I would have to unlock and lock the threads, etc. every time I put in a recipe. It ends up being pretty time consuming.
