To put it simply, never.
To be fair some things they do have an excuse for. In past games, a lot of animations were more tacky and less sleek so they took less time to create. Meshes were also much more simplistic and low poly so they were much simpler and quicker to make aswell. That all means they can create more in less time. And in previous installments, to be frank the build buy and cas that came with packs suckd. Packs were focused much more on gameplay rather than making things look nice.
The main Sims 4 pack that focuses on gameplay rather than visuals is Get to Work, and people complain no end about how much they hate the world and don't like the items that came with it. With that pack you get open for business and multiple active careers all rolled into one which I think were seperate packs in previous installments but people spend their entire time complaining about it as they don't like the world.
But yeah TS4 is lacking in a lot of ways, most of which I blame EA for. Way too many restrictions are put on the developers, they have to push out so many different packs every year and EA don't give them the time, resources, or staff numbers to make solid content. Sadly they're stuck under a terrible company which doesn't give them the freedom to make quality content and values quantity over quality.
