I support it, because it fits logically into the story for DU. Clearly quite a few players wanted romance with Gortash, and forum threads dedicated to Gortash were created repeatedly. If I understand correctly, after patch 6 kisses were changed for all companions, accordingly, Larian has unused ready-made kiss animations of patch 5, why not give a kiss to Gortash? It doesn't seem like such a difficult task, especially if it's not a full-blown romance, but at least a kiss. To be honest, while I myself don't use any additional romantic content (scenes with anyone but LI) at all, but just evaluating these features from the outside, it seems strange to me that you can do this with an incubus, an illithid, a bear, but for a normal man like Enver Gortash who has his own fanbase, they never added anything. Larian, in my opinion, made too strong a bias towards “exotica” in their additional romantic interactions, and to balance this content by adding something more classic and literary like a romance with an intellectual strong male character (now it's unlikely they'll make a full-fledged romance by now, so at least a kiss) would be very good.
For my game, I'd like to be able to keep Gortash alive and make an alliance with him. The possibility of an alliance with him for me pretty much devalues the fact that you know he's doomed anyway, yes it's a metagame, but I'd really like the choice of an ally to be able to influence the story, and not just for the “interest” and roleplay. Besides, I sympathize with this character, Gortash is an intelligent, ambitious character with a strong character and a heavy backstory, who achieved everything exclusively by himself, without any help, and even, rather, in spite of the world around him. And he has to die. No options. I would like the player to have the opportunity to somehow influence his fate.
