I agree twice over.  The larger issue is that logging is part of the 
production environment.  It is meant to serve the ops team; benefit to 
developers follows consequently.

Understand that logging doesn't serve to verify variables, methods and the 
like.  Logging serves to verify correct user-visible function; necessary to 
that purpose logging sometimes verifies variables, methods and the like (at 
jul's FINEST or log4j's DEBUG level).

As you say, logging is an essential component of system design, every bit as 
much as the functional requirements.  After all, no functional requirements 
succeed if the system cannot run.

Logging and assertions are run-time, class-by-class controllable for a reason.
