I for one would at least like an Aloth romance (One person on the internet, forget where, I think steam forums) said you could put additional romances in a DLC so that people who don't like them don't have to get them.
I like both Pillars of Eternity and Baldur's Gate. However, I have finished BG more times than I can count (to PoE's one time) for more than just because it's an older game: I can romance characters (granted the only ones I do are modded), but that's because Bioware's romances there, while the best there is as far as official content, fell short of how good modders made them.
I'm going to guess from the fact that no one's done any, that making NPC mods is difficult for this game. Failing Obsidian wanting to do this, give a tutorial in how modders can make one. (I'm a terrible writer, I couldn't write a bad romance, otherwise I'd write ones for Eder and Aloth)
(if the leads are afraid(for lack of a better word) of not doing romances well, could reach out to the modding community, maybe even the one for BG and find out from them about writing a good romance. In my opinion--and I'm sure there are plenty who will disagree--the people who wrote Edwin's romance and Adrian did a good job. Both can be found at spellholdstudios.net. I recommend going through the forums, though (shsforums.net), since the site has long had a bug that won't let you go through more than one link without spitting up a white page that says "Disallowed Key Characters")
