I think the psychology behind that is that there is no advantage to playing past your prime in D&D. In GURPS there is an in game advantage of free points when you take any sort of disadvantage, so as a result the idea becomes far more feasable, but even then, it really depends on the power level of the game.
Not many people would make an old wizard with 100 point base because even with the disadvantages he'd seem far less skilled than he should be at that age. If it was 300 point base though, he'd be a pretty epic wizard and being old would be the least of his problems
