Since dishwashers have some quite hot programmes, why is it that they
usually only have a cold feed? Washing machines rarely come without a
hot feed, why not dishwashers?

Hot water feed to d/w is advised against as it sets proteins, making
washing less efficient - in my Bosch, there is a heat exchanger which uses the
heat from the outgoing to warm the cold feed coming in for the next phase and
stores it in a transfer tank - the amount it uses anyway is pretty insignificant.
