Do You Miss Imaginary Friends From Sims 3 and Wish They Would Add To Sims 4

I played them a little bit in Sims 3 and they could be fun, but I have to say I haven't thought about them while playing Sims 4, so I haven't missed them at all. I wouldn't mind them being added if you could easily get rid of them or not get them in the first place if you didn't want them.
