How to support multi-architecture docker-compose configuration for devcontainer.json?

Question

In our engineering team we have people using older macbook pros as well as the new M1 (ARM) chips. We currently have 2 different docker-compose.yaml files that pull in different docker images for our data services based on which architecture the host computer is using. This is not ideal, but currently works fine. I want to make use of devcontainer.json so that our app layer could also live in docker to make setting up a new machine within our eng org very easy. The problem I'm running into is I'm not sure how to tell devcontainer.json which docker-compose.yaml file to use based on which architecture is being used.

My current thought is to just have the developer set an env var on their host system that derives their arch and then utilize that env var within devcontainer.json to point to the correct docker-compose.yaml file, but I'm wondering if there is a better way to achieve my goal.

I noticed that there is an open issue within the vscode-remote-release repo but I think that pertains to the app code image that gets built. Not quite the same situation I'm in, but the solution is probably one part of the solution to my question.
