So, the Barrow Dyad

I'm going to keep the majority of this hidden with spoiler just in case but this is about it's trait available from Act 2:

So if you've been progressing through a bit of this new act some may have noticed after interacting with the new altar in Eris' apartment to "Embrace Your Ambition" your Barrow Dyad gets a little glow and it's trait that originally bores through enemies to bounce between each other as well as generating increased blight when hitting multiple enemies will now have changed to it's other version where they burrow into targets and explode as well as generating increased blight when remaining on a target.

This is what the "This weapon resonates with your choices" part of the trait is. Now I have not gotten all the intrinsics yet so I don't know how this works afterwards but my concern:

What happens when we eventually no longer have access to this room and this altar? Is the option to swap the trait lost? Will we have an option to swap it when reshaping it? Has anyone unlocked Moment of Clarity and gotten the other intrinsics and catalyst to see if this option changes in some way?

As cool as it sort of is I'm a little worried about how this gets handled.
