Did we have beautiful antialiasing? no
Were the textures objectively deficient in a lot of places? yes
Could the lighting be improved? yes
The above, I consider a great upgrade and necessary, they fill a void that we didn't have

But the faces? why? What was the point in remodeling them, the system was not deficient on expressions.
Gposers have hundreds of thousands of photos out their with the most amazing expressions that were done with the current system we have now

Not only that, you can improve facial topology without resculpting the entire face.
"Adding more bones" isn't an excuse, you could add as many bones as you wanted to the current faces without changing a single polygon if you really want to go that far
Not only that, it's already been *done* by people for the entire body
