Indeed. That is one of the reasons why I liked Koi Kaze. And regarding Oreimo, that anime ending pissed me off like no other anime has to this day. And what they did with the VN was well... not the ending we needed, not the ending we wanted, but in the end... it's the ending we got and it's better than nothing.
I'm hoping that Yosuga no Sora takes it seriously, but if it was as serious as the shoddy anime adaptation, then meh. It's kinda treated seriously, but I don't think it was as agonizing for the characters as in Koi Kaze, since well, Sora
