Think of the Dark Curse and how Rumple bluffed at getting their happy endings with the Dark Curse. The Dark Curse doesn't need to traverse lands (see Pan's curse). The Dark Curse just has the possibility to traverse realms and was simply used to do that because Rumple convinced Regina to take them to a land without magic and Snow knew where Emma was.

In the example that I gave, the Prince wouldn't be happy for the death of his father, but he changed the entirety of the realm and their is untold happiness. Happiness, not happy ending necessarily.

It could help King George. Wipe the memories of David and all the realms. Have David be the Prince he wanted him to be and his kingdom rich and prosperous.

It could help Hook. Take away the magic and Rumple is powerless (in theory) and kill him.

It could help Ingrid. Take away her "sisters" memories and have everyone else see the worst in others and kill themselves.

It could help a lot of people, but the cost is what deters most.

To think that the Dark Curse that :

CAN traverse realms/worlds, CAN erase and supplant memories, CAN stop aging, stop time in many realms, CAN bring magic or not

is just some powerful magic bean would be foolish. Can doesn't mean will or can only.

Since it was never used in another capacity, we can not say, but we also can not limit it either. Pan's curse simply would have made it like timeless/ageless/memoryless and like it was before.
