Airspace and approach design play a big part in this now too. How often do you get to actually do a visual circuit? For the QF 767 drivers, there is only a couple of places where you can fly a proper base and final approach let alone joining downwind a circuit altitude.
With an increased focus on the automatics, QARs, speed tolerances, and so on there is also an increasing focus on programming the FMC so that you can actually leave it all engaged for as long as possible. Training departments themselves are breeding this in so it'll be interesting to see where we're at in 10-20 years time when the current breed of new F/Os become training captains.
