Should the next Sims game go above the T rating?

I agree that Sims 4 is probably the most ''immature'' or ''childish'' of the four series. I think the whole Emotions playing a part in their daily activities like taking a p00p goes too far.
I do however like that, while talking about the subjects of the Emotions, you can make certain dishes while having a certain emotion (gummybear pancakes for example and the protein thing).
