Another `buildx` question, this time pants-specific: is it possible to add multiple `cache_from` entries to `docker_image`?

Relevant docker docs issue: <https://github.com/docker/docs/issues/8531>

Seems like pants doesn’t yet support this yet. I guess the cache_from arg would need to be made more flexible. Can you file a feature request issue?

Thank you! That suggestion sounds like a good one. Is that something you’d be interested in contributing to pants?

Nice! As a breadcrumb, it’s the `DockerImageBuildImageCacheFromField` type and its uses that need to be adjusted: <https://github.com/pantsbuild/pants/blob/main/src/python/pants/backend/docker/target_types.py|https://github.com/pantsbuild/pants/blob/main/src/python/pants/backend/docker/target_types.py>
I’m on mobile now, so I don’t know how to get the “list or single” behaviour. Feel free to pop over to <#C0D7TNJHL|> and ask if you need
