A possible follow-up would be to provide a script for installing the CLI using basic tools. POC (with an older version):

#!/bin/sh
set -e

mkdir devcontainers-cli
cd devcontainers-cli

wget -q -O- https://registry.npmjs.org/@devcontainers/cli/-/cli-0.49.0.tgz | tar xz
wget -q -O- https://nodejs.org/dist/v18.16.1/node-v18.16.1-darwin-arm64.tar.gz | tar xz --include node-v18.16.1-darwin-arm64/bin/node

./node-v18.16.1-darwin-arm64/bin/node ./package/devcontainer.js --help
