Surely the future S stock would have made a much better base vehicle
for this sort of application?

Dunno, but there is no excuse for 2-car DMUs to be being used on this
kind of service. Nor should TfL be running 3 cars on the Watfords
when 6 would fit with a bit of power upgrading.

The whole of LO appears to me to be an almighty expensive cop-out for
a capital city. Look at Merseyrail for how it should be done (and
without any new MUs), then try again.

Merseyrail isn't a good example of how it should be done. The entire
electrified system including the loop and link lines were designed for
six-car operation, then after a very short time the trains were reduced to
three cars - which is why SET and LO ended up with Class 508 units.
