Some of that did actually happen with AMD64, so dropping 32bit support would be a step in that direction.

Almost no one else is in Apple’s position of vertical integration though, except perhaps for the console makers.

With AMD64? I thought that was completely backwards compatible with x86. Or do you mean IA-64?

The CPUs can also run x86, but the AMD64 instruction set itself (now commonly and incorrectly called x86-64) is significantly cleaned up.
