According to the new Wowhead post, there will be a dialogue between Tyrande and Sylvanas:
Pelagos: Sylvanas Windrunner. There can be no true justice without compassion and I can see your deeds bear the mark of the Jailer's influence, an influence we failed to contain.
Pelagos: Then you know in your heart to whom you must answer, in trusting justice to your most fervent adversary.
Pelagos: Are there any gathered here who object to this fate.
Pelagos: So be it.
Sylvanas: The Jailer did not control me. Death would be a merciful end Tyrande. However long it takes.
Tyrande: What game do you play now Banshee?
Tyrande: The Sylvanas I hunted would never submit to the blade of her enemy. Your newfound remorse might be genuine. There will be no peace for you Windrunner.
Tyrande: The prisoner is in my charge now.
Tyrande: Below lies the Maw. Every Soul lost in its depths, betrayed or condemned, you should find and send forth to the Arbiter. You will toil there under Dori'thur's watchful eye. This is how you shall bring renewal to your victims. <Darnassian>, old friend. Watch her well.
Pelagos: The time for your judgment is at hand.
Sylvanas: My actions were mine alone and I accept their consequences and I do not expect your mercy.
Tyrande: But it can never erase all you have done. Until there is peace for the souls of your victims.
Tyrande: Bring her.
Tyrande: An unjust fate to which you doomed so many. And it will be there that your penance begins. To be judged with the compassion all souls deserve. Scouring every darkened reach until the final soul is free and you are all that remains and my people.
Tyrande: It shall be done.

So here Tyrande tells Sylvanas that she has to go to the maw and free the souls she condemned to it... except the Night Elf souls:
"Scouring every darkened reach until the final soul is free and you are all that remains and my people."
Back in the Ardenweald campaign in 9.0, we freed a small fraction of the Night Elf souls (around 100), but many many more than 100 died. Over 900 died in Teldrassil alone, and many many more in Ashenvale and Darkshore.
We never went back to free the remaining vast majority of the Night Elf Souls in the maw, and now Tyrande says that Sylvanas has to free every soul but leave her (Tyrande's) people in the maw to rot?
Or is the implying that the souls of her people are already obliterated and that only their soul ash / anima remains, and thus she refers to her people remaining in the maw.
It doesn't really make sense, it seems like Blizzard is so obsessed with making the Night Elves suffer and not giving them any positive development that they forgot that it would be extremely out of character for Tyrande to advocate for her people to remain in the maw. If anything, she should be telling Sylvanas to free the Night Elf souls first because she condemned them to this place which would be the opposite of what she's actually doing.
Blizzard has been trying very hard to not give the Night Elves any positive development in both BfA and Shadowlands and thus it's obvious that the Night Elf Souls (and thus the vast majority of the Night Elf race) would end up getting obliterated in the maw instead of freed, but now even Tyrande says that Sylvanas should free all souls except the Night Elf souls... what?
