If you really believe there is not much to do to finish what you have listed, then you are delusional.
Liandra's quest wont go forward without the implementation of Kirlic.
Gavina's story has barely started, and it will probably involve the dark elf we've seen, so that will most likely be a lot of content.
The queen and princess just got introduced a few updates ago and, as I said before their story is linked with the orcs and the war.
Tia is kind of finished, her father is dead. Any potential future quest with her will surely be about the orcs and that wont happen before the queen and princess.
The cult involves Thomas, Giron, Roderic, Lucius, Coldstone, the demon we saw when checking the basement of the inn and maybe Arianna. That's also requires to progress Penny and her sister.
For Isha and Athia, it will take a lot to finish if it's not rushed.
Mira's progression could be tied to a lot of other things : the war, all the girls from the monastery, Syfa and maybe the demon from the cult, and maybe even Isha and Athia (all this list is pure speculation from me).
And since you are talking about unfinished quests, here is my quest journal, I've finished all the available content with the exception of Emily's wedding.
So you forgot Melissa, Kate and Ophilia who also require the implementation of Kirlic.
And Anya's story, once again, as I've said before, is tied to the war and thus to the queen and princess.
So in conclusion, most things that need to progress for now are pointing towards Kirlic.
And the rest is pointing towards the cult or the war/the orcs.
All of this is slowly tying in together but it will take a lot to get there and Kirlic is bound to happen soon.
