My guess is just to save cost. The R/T Classic pack is a value-added pack so it makes sense that they would add them because it justifies a higher cost. Reducing cost on the R/T is a bit more important to make it a better value against the rest of the muscle cars in this price range.
I'm sure the 6.4 produces a considerably higher amount of heat than the 5.7, so it makes sense to have them fully functional there.
