Hi, can someone please explain the deal with the dark brotherhood patch notes

"You will have full knowledge of all Equipment Traits, including Nirnhoned."
“The Crafter’s Limitless Library” contains the full Style Book for every Style that your character does not know. This allows you to pick and choose which styles you’d like to learn, or you can just read all the books and learn everything.

I hope this doesn't mean all my research time learning every style and trait and also the vast cost is wasted.
does it mean anyone can instantly learn everything.
