Given the way we do logging now, I'd say I mostly agree with Scott and
Rod.  Making it an interface makes it public for no clear benefit (at
present).

That said: Back awhile ago when we settled on the convention of logging
in the IdP with a prefix containing the component name, id, etc, I was
thinking that it seemed desirable to streamline and automate all of that
somehow, if possible.  I wonder whether there is some way to take
advantage of SLF4J and/or Logback features that we have never used, or
maybe extensions points (custom layouts, appenders, etc), to accomplish
this without making the class doing the logging do it all manually. 
Ideally it would be something minimally invasive the class doing the
logging.  Perhaps a topic for some research.

I mention it here b/c:  if there (hypothetically) was some way to attach
or associate the logging class instance to the logger, then the
interface could be used to pull the log prefix out and prepend it to the
log message, either via the layout or a specialized logging component,
etc.  If something like this were possible, then having this interface
makes a lot more sense.
