There's millions of man-hours invested in optimizing software and hardware for the ARM64 ISA. Abandoning that for a nebulous "we can optimize for our stack" is not a worthwhile tradeoff.

Apple previously co-developed PowerPC with Motorola (and IBM) for this very reason. At this time, Apple has all but kicked its third-party developers out of kernel space on its operating systems which will make for easy transition to future architectures. I would go so far as to speculate Apple is already designing proprietary RISC-V extensions and even their own FABs to produce them. One would expect such extensions to help Apple's systems execute Swift and ObjC better (faster and more securely) than general purpose processors and to optimize shared memory and fabric access between CPU, NPU and GPU cores.
