I'm curious... why it would still end up being only 6-8 flights for even a
replacement/successor program?

What are you going to do with more than 6-8 flights a year? I guess
it's possible that the shuttle's successor will be the super
spacecraft which can fly from a normal airport and do everything we
might want with 99.9999999% reliability that we've all been waiting
for, but it seems more likely to be a limited taxi to fly to ISS and
back... not much use for it other than the odd crew change and cargo
flight.
