That might have been me, and was mostly a reaction to the extreme exaggeration of and sole focus on Spawn Astarion's limitations by vehement opponents of the spawn ending. I like how the sunlight situation is treated in my Origin-Astarion game with romanced Gale. When you worry that Gale may not be completely happy with you in the eternal night, he'll say "I won't deny, our living arrangements have taken some getting used to. Though you remain a ray of metaphorical sunshine amidst the darkness, as ever." It's a bit bitter sweet and I love it. Personally, I think, Astarion will just adopt an as cavalier attitude towards sunlight as Spike from Buffy does.
