CPU op-code 32 bit with Rosetta2 emulation under vz

Description

starting colima with

colima start --arch aarch64 --vm-type=vz --vz-rosetta

my docker-compose file is

version: "3.9"
services:
  dds:
    build:
      context: .
      dockerfile: env.Dockerfile
      ssh:
        - default
    platform: linux/amd64
    environment:
etc etc

If I spin everything up this way I get

Architecture: x86_64 CPU op-mode(s): 32-bit

If I do --arch X86_64 I get the expected

Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit

My understanding is that the way I'm doing it with aarch64 is the correct method for running an X86_64 image emulated on Apple Silicon. I would go with the second approach, but working on it is so slow as to be infeasible. Being only 32 bit but having a 64 bit OS/development environment will be problematic
