Unfortunately, yes.
I had to start a poly romance with Halsin using my second Tav, a paladin, who is in relationships with Astarion, for scientific reasons - I wanted to check after-drow dialogue with Halsin in patch 5, wanted to see if Larian really expanded it and added this "trauma" thing (unnecessary expansion for even more unnecessary dialogue, IMO). And then I reloaded a save file and rejected Halsin.
So, from my personal experience (I've seen some scenes with Astarion and Halsin poly romance, so I was ready) I, as many other people, think Astarion doesn't suit for poly option. Yes, he says he's ok with Tav being with someone else and yes, maybe I am overthinking, but I felt I am betraying Astarion, especially considering what life he had before. My paladin is an ultimate good guy who is trying to show his beloved vampire there are good things in people. But this is my personal roleplaying. I think the same goes for people who romance SH and see what life she had before, there are many people who want to "protect" her and make happy, but in this case we have a writer, who wrote both her and Halsin and his hands had all freedom to do what he wanted.
To be honest, sometimes I think maybe John is not the original Halsin writer, considering how drastically poor druid was changed.
