Unused Stygian Abyss "resources"

[Nystul]

There's a number of items that were introduced with SA that resemble & relate to the other Imbuing crafting ingredients. But, they have no current use.

Here's a list obtained from the UHall thread titled "SA Loot Drops, Their Sources and Uses"; http://vboards.stratics.com/showthread.php?t=156965.

Essence of Persistence
Fey Wings
Fur
Horn of Abyssal Inferno
Kepetch Wax
Lodestone
Primeval Lich Dust
Slith Eye
Vile Tentacles
Void Core

(List edited to remove descriptions to keep it shorter)

Are there plans to make all those items, or some of them usable at one point? Or would it be safe to stop collecting them & toss them out?

Thanks
