Undroppable items

There are some weak undroppable items like the Amulet of Whispers and the Holy Symbol of the Three that are clogging up space in my vault.
I understand that the Amulet of Whispers wouldn't be possible to drop during the quest because it is still needed but maybe it's possible to add a way to remove it afterwards like giving/selling it to captain Torden so he could destroy it?
And I have no idea why the Holy Symbol of the Three couldn't be sold/dropped. I get that Hirge might be attached to it but it was possible to sell Azaph's Ring of Elements even though Grissenda cared about it so I don't see the difference. Maybe it is still needed in future quests?

I think the developer hinted at the fact that Syllara (the lady from the lady of the night quest) may come back in this next update that is probably why the amulet can’t be dropped and the holy symbol of the three is probably part of hirge’s companion quest
