Moreover, you can pair it with drift detection (available in i.e. Spacelift[0]), and have it automatically detect when a data source changes (and apply the resulting infra changes).

Very common scenario with lots of neat use cases around it. One of the more interesting ones - use a GitHub pull request listing data source to create an ephemeral environment for each PR.
