Eh, personally, from all the things I've read in both ingame and out, I think it was just cut probably because they couldn't finish it in time (I mean, they didn't even get the original epilogue done in time (of which you can still find on youtube))
I mean the alternative is that they added all this stuff that makes you think she can be saved but go "Sike nope, she's gonna die. This special infernal iron was always meant to be merchant fodder. This conversation with her merchant friend also means nothing"
In saying all this, I don't particularly care for her as a character in the game tbh, she's fine as a person but her story and personality don't make much sense.
Maybe they'll do something with a potential Definitive Edition but going off of how they implemented this new epilogue, it doesn't seem that they'll implement it in whatever way they may have originally intended.
