True, new products like microfiber have taken over and left things like cheesecloth in the dust. Microfiber is softer, stronger, washable, and has more uses than just removing wax.
Ahhh yes.... cheesecloth, cotton diapers, and flannel by the yard. Combine that with Rain Dance, Polyglycoat, and the 2-stage acidic wheel cleaners from Eagle One and you can have a retro detailing party.
