Other use cases might be that we can replace the variable backend with other storage like S3 and support both read/write. It seems like `Variable` is now tightly coupled with `SecretBackend` for DAGs to retrieve secrets from Vault. However, I have seen Airflow users that use `Variable` to share data between tasks/DAGs (yes they can also use xcom but they still can choose to use `Variable` as long as it exists) so it's usage is not limited to retrieving secrets. As long as `Variable` support a set method, it can be confusing to the users that they thought they can set a variable backed by Vault, which they actually can't. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
