Please fix that part where random sims join in conversations during a date

The Mod Remove Sims from Conversation from thepancake1 and MizoreYukii are very helpful to kick townies. I wish the Sims team would ad this feature in a vanilla game or that you need to invite stranger in your conversation. All sims are social butterfly (self sims which have the loner trait). If I want this, I would invite you or start talking with you.
