For the love of God, no, we do not need even more pandering to the people who obsess over these characters. The constant catering to fanservice is why the game is in the state it's in now and why the story has gone completely down the drain, because the writing exists to serve as a set-up for pointless asides designed to set fans aflutter instead of developing a decent narrative. If you're longing for that sort of content, go play Baldur's Gate or something.
It blows my mind how different gaming communities are these days, and how strong fan influence has become and the level of entitlement that brings with it. At the risk of sounding like a grandma, time was you played something, you enjoyed it, and you shared all your thoughts and feelings on the characters and relationships with friends or fansites and made your own content if you so wished to - you didn't ask for your own headcanons to actually be put into the game.
The devs are most at fault for feeding into it and encouraging it, but I think some fans really need to get a bit of perspective and realise that sort of thing belongs on AO3 and Discord servers, not in the story itself.
