I believe that this is trivially simple (providing a holder vwith a object
renderer in the toString()) but that by providing the holder class in SLF4J the
best-practice approach to handle this is in intent and action shown by SLF4j
(which also is a trivially simple (or used to be :) ) approach to the "facade
to logging platforms" problem.

In other words, by providing a base class to override in anonymous functions,
slf4j actively promotes best-practices regarding how to render an object as a
string.

Another approach could be an interface containing a render() method which could
be implemented by objects.  If an object is tried to be logged AND implements
this interface, then the render()-method is called, otherwise toString() is
called.

Just a suggestion :)
