Thanks, gonna review soon!

This is a very clever approach. However, I'm hesitant to merge it right away, as our current Docker test isn't very costly and it's the only test that would benefit from this PR. I greatly appreciate your effort to improve this. In the future, if we have more expensive tests, I will definitely advocate for this change.
