I would not mind it, but I think they should focus on making on making their premades interesting and not just add them for the sake of representation, and also make them work with the pack that they are making.
I watched one twitch streamer visit the Tinker household and he could not even understand that they were a couple because they did not even behave like they were married, they both started flirting with his male sim because of the Free Love NAP.
I want interesting premades that people seem to come up with on the gallery, like single dads for example and make them have interesting relationships in the game. Imagine if they would add two male sims that were romantically involved but not even living together for example, and it was up to the player to discover it themselves.
