Considering that GitHub actions provide no arm64 runners at this stage, this could be extremely useful for some of my projects.

So when I build a project on GitHub actions, I simply add a `platforms: linux/amd64,linux/arm64` line to the Docker build & push action. This takes care of pushing the multi-arch build to GHCR for me. Would it be as straightforward in Depot as well? Or would modifying the image manifest be my only option?

It should be just as as straightforward with Depot as well - we have a depot/build-push-action (https://github.com/depot/build-push-action) that accepts the same inputs as docker/build-push-action to make it easy (under the hood, both use BuildKit).

    steps:
      - uses: depot/setup-action@v1
      - uses: depot/build-push-action@v1
        with:
          platforms: linux/amd64,linux/arm64
