Life without MCCC Story Progression

I'm pretty sure through out all version of the sims 4, townie won't get married on their own and have offspring (even with ECO lifestyle, the rate of you receiving the have baby phone call is still quite low.) And They also hardly move into empty lot outside of the world your active household are lived in. That's why people use MCCC to make sure there won't be ghost town and the Landgraab won't just die out after Michael get old.

Since the new update won't implement these two aspect of story progression, I believe the game after the first generation still wouldn't change that much.
