Not at all.  If you are unsuccessful and did not issue an error message,
you have a bug to fix.

When a command finishes successfully doing what it was asked to do,
especially when it does a lot of things and has potential to issue useful
error messages and warnings to some but not all of them, it should stay
quiet for successful ones unless there is a very good reason not to.  The
reasons may include "the user told it to be chatty with --verbose", "it
may make the user think it hang, because it takes a long time", and
perhaps "it is a rare thing to run and the user may not be familiar with
how it acts".
