The worst of the poorly aged material didn't even survive the original game's lifeline. Some early books were published with that material. Many of those early printings were shipped with a sticker covering the questionable material. Printings after the books with the stickers completely excluded that material. The ink wasn't even wasted on it.
The copy of the book I bought around '93 or '94 doesn't even have that material.
I doubt they would put it back, considering it was even considered "too far" thirty years ago.
