- Using an API with ChoiceType/EntityType: how to optimize data loading?

- Using PHP7: how to handle validation for strict-typed getters/setters?

- Using sensitive data: how to handle permissions and fields visibility?

- Using symfony 2.7 and older: how to rethink some form types while migrating?

- Using multi-steps forms: how to keep control of submitted data?
