for better visibility. When not in a task, warnings from these helpers
are only logged to STDERR, which is particularly unhelpful in case of
daemons. This is the main motivation behind this change.

For tasks, warnings from these helpers are already more visible on the
UI side, but when looking at the syslog, one can only see the warning
count from the task right now, not the actual messages. This is
another reason in favor of the change.
