I don't think any romance needs to be added to the game. Romance with an NPC is kinda pointless, and rather unfulfilling. Much like kissing your reflection in the mirror.
My disagreement with this particular addition to the game, is more about privacy. The key problem with romantic options with NPCs is the "group factor".
Regardless of how you feel on SGR content, you have no control on these conversation outcomes if someone is grouped with you, and they happen to roll higher on the conversation option.
SGR content, just like ANY romantic option, should be EXCLUSIVE to companion, or single player conversations. Your romantic choices should not be made public, in any way.
Except OGR flirts are already in group conversations. So I guess you'll just have to deal.
