But we do provide an abstraction API, and in fact some of the design in has a bit of a LCD feel to it. For example, we do not have a Logger.setLevel() API.
For good or bad, some folks DO want an abstracted logging API, and this is required to get a large stack of 3rd party components working together WRT logging.
