And it will continue to break, for dumps from pre-7.3 databases.
I think it's a mistake to spend much time on trying to solve that
problem; it'll just distract you from solving the presently-useful
case.
I don't want to see the behavior get a lot worse for old databases,
mind you; I'm just saying it doesn't have to get magically better.
