Blocking callbacks

[DanielDuranSW]

Could you clarify the future support for registering callbacks on dbt's EventManager? "The current behavior blocks subsequent steps, but this may not be guaranteed in future versions". "Given that the Python interface for events is less mature than the structured logging interface", would it be better to rely on parsing JSON-formatted logs for handling real-time events, or are callbacks still the recommended approach for this use case?
