I have no idea if devs actually consider feedback much generally, unless highly upvoted, and highly asked for across platforms. But this has been long asked for so I think, and still hope there is a chance.
I think in Sims 3, if compatible they had slight social and/or romantic advantage and if incompatible a slight social and/or romantic disadvantage. In the Sims zodiac depended on how neat/outgoing/active/playful/nice a Sim was. It would be great if zodiac did more that compatibility/attraction, but I'd be fine if that was the bare minimum too.
