People dislike romance in games because it tends to be poorly written, and encourages players to fill an invisible affection meter as some sort of metric for human relationships - sometimes the meter is plain as day, making the system even more embarrassingly gamey.
That said, if romance in PoE was held to the same excellent standard as the rest of the game's writing, what's the problem? Are people worried it'd foster a certain waifu element in the community? That seems like more of community management problem than an actual concern with the game. In my perspective, the more choices and opportunities afforded the player to roleplay, the better. Having the option to instigate a romance with certain characters could only help further flesh out your character and their story. So long as it makes sense within the narrative, what's the problem?
