Those restrictions only apply if you want to field a very specific Thousand Sons force, or a Death Guard or World Eaters warband. They are more for determining whether you have a fluffy army of that type.

Point is, the real difference lies in the fact that if you keep to the restrictions, for example the World Eaters ones on page 45 of the index, you don't get to include daemons in your World Eaters army. They are not on the list (pages 16 through 42 inclusive). However, you do get to use Khorne Berzerkers as Troops instead of Elites. The same goes for the other legions mentioned. Thousand Sons have a restrictive list on page 49. No Tzeentch Flamers on there, no Changeling or Blue Scribes. But they do get to have Rubrics as Troops.

Opposite that, you can have an army with (Elite battlefield role, not Troops, note how the list on page 49 specifically refers to the Rubric Marines on page 54 and not those on 29) Rubric Marines and a couple of Tzeentch Screamers and what not. The army would still be battleforged, as they all share CHAOS as faction keyword. However, even if everything has a dedication to Tzeentch, they are not Thousand Sons.

That's incorrect. The boxes simply tell you what units can have the legion keyword in question, not which units you can include in your list. So you can very much have Rubric troops and still include anything else chaos in your detachment. There will undoubtedly be benefits for picking pure Thousand Sons for your detachment in the future, but those benefits do not currently exist.

Well that's what I'm wondering and why it was so confusing. They give you this list, here are all the things that can be thousand sons, but it confers no apparent benefit whatsoever, instead it makes it appear you're very limited in what you can choose. Until you realize, oh, everything has the chaos keyword, I can include any mix of things I like in a battle forged army. Leaving with a giant, what the heck is the point of all this wording lol.
