Look at your first statement and then see that it is not a direct implication:
So my answer is valid to your statement as I said:
As I said when I brought as an example where it all began, that nobody can say its animation are not beautiful, as his renders, it is a matter of benefit and cost. The key fact is that for what they bring, they are not worth the cost, in terms of money and time, almost all the time.
In a perfect world, we would get everything, but we have real life limitations and almost every scene can be done correctly with a few renders.
No need to clarify, but I will do it before somebody answers, these are my opinions, of course.
