Additionally, a background task is normally an independent set of logic that should be handled separately, with its own resources (e.g. its own database connection).

If you used to rely on this behavior, now you should create the resources for background tasks inside the background task itself, and use internally only data that doesn't depend on the resources of dependencies with `yield`.
