Pros & Cons

- Stack drift and stuck rollbacks can be painful to unwind
- Real languages: types, tests, IDE autocomplete, shared packages
- Open-source engine with a free self-managed state backend
- Can use Terraform providers for long-tail coverage
- Moving from Terraform is a rewrite, not a binary swap
- General-purpose code makes it easier to write clever, unreadable infra
- Smaller hiring pool than HCL
