this statement is not true for the general case. Logging *may* be an
auxiliary feature, i.e. when thinking about debug output that's of
interest mostly for software developers, but there are applications that
must leave a reliable audit trail, i.e. systems that deal with money and
finances. For those applications, logging is part of the business logic.
The same is true to some extend for applications that run in the
background, like network servers, etc.

However, users that do want to deal with those exceptions themselves
should be able to.
