I'm curious what problem this solves. Especially since the Apple Silicon switch, I think most people are aware of how to address architecture inconsistencies with Docker. In general, the global solution is just to set DOCKER_DEFAULT_PLATFORM, and a quick googling will pull up even more succinct guidance on StackOverflow.

I'm a little hesitant to treat this as a specific enough problem to document or build explicit code around.

I do see that there is a problem around the architecture binary for the CLI. Can we not detect the architecture using something like uname and then dynamically download the appropriate binary?

Why are we talking about Apple silicon support here?

The runner binary is Linux based. It does not run on Apple silicon nodes right now.

I have the same question as @relwell - what is it we want to accomplish here?
