It gets confusing that Gods can not die. Since that would mean they are immortals. And the rules for immortals should also apply to them too. Yeah, but the HG users are weak to the thing that gives them powers. They aren't naturally immortal. The HG/ Excalibur can take the eternal life and magic away from its users, not the gods.

The show hasn't retconned it yet, so we can't speculate. So far, the HG gives and can take away its blessing/ curse, but it has no significance to Hades whatsoever. There's a reason why Rumple was scared that he could be killed by the river of souls and not Hades. It's probably because Gods are beyond that. Even Rumple couldn't raise the dead, but Zeus clearly did.
