Perhaps there will be an intermediate step where they drop support for x86-64 executables, but retain support for x86-64 virtualization. That would still let Apple slim down the macOS system frameworks to a single architecture like they did previously when they dropped the x86-32 frameworks.

There is no support for x86-64 virtualization on ARM Macs. Do you mean dropping support for Rosetta for macOS apps but keeping support for Rosetta for Linux VMs (which run ARM Linux kernels and use Rosetta to support x86 userspace software)?
