I don't believe taking out questionable overwrought performance voodoo would constitute "redesign[ing] their cores from the ground up". Just like any other form of engineering, you know when you've solved a problem, and you know when you've made a hail mary pass. Take out the hail mary passes. In most other areas of engineering where there is still some concept of liability, the process is: validation first, save hot-rodding for v2. CPU industry is largely unencumbered by liability, driven by specious benchmarks, and has no use for that process.
