Even more criminal mischief was deleting the Dies Irae from all the ritual books for funeral Masses and Masses for the Dead, although it is STILL legitimate to use it.

I think Berlioz uses it in his Symphonie Fantastique! Indeed the Requiem Chant is used quite a bit by Classical composers. A wonderful example is Durrufle's Requiem, 20th century but gorgeous.
