The fundamentals are actually more-or-less identical to what they were in 1988. The crucial point (which to the best of my knowledge has always been in FCTM/FCOM etc.) is that in ALT or Direct Law, it is possible to stall the aircraft.
DIRECT law is a very degraded control law (not at all like a reversion to conventional control system). You could never certify an airplane with such system.
How so?
In the 330 DIRECT law comes in fewer occasions. You can land in ALTN (it has a flare mode)
You can land in any mode on any of the Airbus FBW types- how do you think they did the flight tests? The only addition Flare mode makes is requiring a degree of gentle, progressive back-stick to simulate conventional input to some degree. In Direct Law as long as you use the ADI to manage your flare you should be fine!
