I think it's more that it's only necessary now. It's such a pain to make that you'll only do it given no other option. A lot of what modern processes are going was possible ages ago, but it was basically always better (in terms of ease for performance gain) to go smaller instead. Now that smaller doesn't help so much, you can see them pulling out all the other tricks in the book to try to improve (and costs going up as a result).
