Same here.
The one place I would consider using a dork disk is with a normal low rear derailleur, such as an old bandspring Cyclo or Simplex. One cable snap or shift lever slip could throw the cage into the spokes. These often came with direct rod control front shifters, as in the 1960 Varsinentals, making for what I call a double suicide transmission.
