### What needs to get done We should include an upstream version of the [schema generator](https://github.com/canonical/rockcraft/blob/main/tools/schema/schema.py) and a [Schema validator/diff checker](https://github.com/canonical/rockcraft/blob/main/.github/workflows/schema.yaml) CI job in craft-application. ### Why it needs to get done We should know when a change is going to affect applications' schemas so we can include that fact in the changelog. While this might not cover every possible case, doing it will still improve things significantly. Perhaps we could generate separate schema files for all of our fakecrafts (testcraft, partitioncraft, platformcraft, witchcraft) to test more scenarios where the schema could change.
