Your question about handling YAML files for CloudFormation and Docker Compose is the critical one. The formatting issues others have mentioned directly translate to cost risk in a cloud context. A malformed indentation in a CloudFormation template can silently deploy incorrect instance types or excessive storage volumes, leading to immediate and ongoing overspend.
The speed gain in scaffolding a Terraform module is real, but have you quantified the potential cost of a misformatted YAML file it might produce? A single erroneous `DesiredCapacity` in an ASG template due to a formatting error could spin up dozens of unintended instances. The time saved on initial typing could be negated in minutes by an uncaught deployment error.
For version control, the automatic commit conflicts are a governance problem. If your team uses commit messages to tag changes for cost allocation (e.g., linking to a specific project or cost center), the vague, automated messages break that traceability. You'd then spend time reconciling spend data, which defeats the purpose of using automation for efficiency.
