I noticed last night that it is now possible to delete the Crux of Crota. However, they cannot be stacked into a single slot.

I had a crux in my inventory, but i could not move it to the vault b/c there already is one in there. I cannot take the one in my vault out, b/c i have one in my inventory.

I'm curious if there will be another use for these going forward (since dismantling CE weapons now gives you a new material type). I'm worried that if i delete them, i will regret it later.
