In fact, I'd actually prefer the option of being able to choose to buy
special cheap-rate tickets that give even less choice than at present,
for those times when they're the best option for my journey.

Take for example, a return ticket between Gipsy Hill and "London
Terminals". At the moment tickets are valid to and from any of
half-a-dozen terminals, by almost any possible route. But if I know in
advance I'm going to London Bridge and returning from there, it would be
great to get a London Bridge only ticket, which cheaper because I don't
have to pay for the availability at Victoria, Waterloo, etc.

What makes you think it would be cheaper?
