Romancing in RPGs is one of those things that i feel every game would lose zero value over simply not including. Hell romance in most forms of entertainment, including movies and TVs, tend to detract from what would otherwise be a perfectly fine story and it becomes a rather senseless inclusion or dramatic angle. Especially in games like D:OS2 where one selecting one rather vague dialogue choice can result in romance, a toggle option wouldn't be a bad thing. Sure the Fane romance was amusing at least, but man it was too easy to stumble into it. Ultimately I'd prefer if the genre alltogether just stopped with this weird fascination with romancing pretend and often questionable characters, but a toggle would be a sufficient substitute.

I would much prefer that any/all assets/resources that went into making romance went into making more, non-romance content instead. It's an easy thing in P&P to have romance if you want it, or don't, but in a video game which is a finite, created world with limited resources and assets working on it...i'd rather just play a game based on romance if i really wanted romance.
