interface FileAccessFormatterControlHandlerInterface in Drupal 8

Defines an interface for file access handlers that need to run on file formatters.

\Drupal\Core\Field\Plugin\Field\FieldFormatter\EntityReferenceFormatterBase, which file and image formatters extend, checks 'view' access on the referenced files before displaying them. That check would be useless and costly with Core's default access control implementation for files (\Drupal\file\FileAccessControlHandler grants access based on whether there are existing entities with granted access that reference the file). But it might be needed if a different access control handler with different logic is swapped in.

\Drupal\file\Plugin\Field\FieldFormatter\FileFormatterBase thus adjusts that behavior, and only checks access if the access control handler in use for files opts in by implementing this interface.
