Howdy,

I accept your point on this, as I don't use AsyncAppender and thus
haven't run across this.

This, too, is an interesting point.  So you have multiple pre-compiled
(and mostly unused?) renderers and change which renderer you use at
runtime?

I haven't had the need to change the format of my logs in production, so
I haven't run across the second point either.  But it's interesting ;)
