While it's not good to use halon in a semi contained space like an airplane, it is incredibly effective at killing fire. It really sucks the heat out of it. Thus in most cases the fire is killed quickly and not much toxins are produced. This is important too because fire itself produces a lot of lethal toxins too, most people in a fire don't burn to death but get poisoned by the smoke.
So it's a big loss imo. I understand why because it's one of the most potent ozone layer killers. But still.. you're not using the stuff unless you have no other choice. If you're not using it it doesn't end up in the environment.
In this case it didn't work because the cargo bay in question was not fitted with extinguishers if I remember correctly.
