Does The Sims 4 require a trait overhaul?

Those comparisons were very interesting to read, thanks for putting it all up. For me traits overhaul doesn't even start to describe everything I would like to have different with personalities, but it sure would not hurt.
From another point of view, I'm sure that there're enough people who are content with it and would resist such huge changes so many years after the game launch which makes me think that it would be better to just leave things the way they are and start anew in The Sims 5.
