Warm rinses for wool are only good if one washed the wool in warm water. Sudden changes in temp can cause wool to shrink/felt. In fact one is best off using cold water to both wash and rinse wool. Warm water was better for washing wool when soap was the only product around for the task. Woolite, and other SLS/surfactant based products clean wool quite well in cold water.
Warm water rinses, were widely used when soap was the main "detergent" for laundry. Even after detergents came on the scene housewives still used/prefered warm water rinses at least for whites/colourfast items as it was believed warm water rinsed better. Warm water does rinse soap better, but cold water is fine for today's modern detergents. When using soap one does not wish for textile fibers to "contract" suddenly, trappping dirt/muck and soap residue within fabrics.
IIRC once the "energy crisis" of the 1970's hit, warm water rinse options began to fade from washing machines. You certianly wouldn't get one past the "Feds" today.
