I recently had a problem where a non-trivial error was logged to the StatusManager, but no StatusListener was defined.

StaticLoggerBinder does have a:

      if(!StatusUtil.contextHasStatusListener(defaultLoggerContext)) {
        StatusPrinter.printInCaseOfErrorsOrWarnings(defaultLoggerContext);
      }

but this didn't help because the warning occurred after this point.

I think it would be useful to log a warning when no StatusListener is registered. Users who really really don't want a StatusListener could register a 'NoopStatusListener' or something similar.
