I don't think it matters. The new formatter is certainly going to be slower
than the existing one. But the idea is to only use it where it is needed. The
proposed way of doing that is via having a unique logger factory. That is
really where I have an issue. The main logger factory should be able to return
an XLogger or some other type of logger. This could be handled via
configuration or annotations or a "marker" on the getLogger call. Creating new
Logger factories for each extension isn't the right answer.

I would also love to see concrete tests comparing logging 10,000 records to a
file using the current formatter vs the enhanced formatter. If the I/O overhead
makes the difference minor than it might not even be a problem to have it be
the default formatter.
