In general, CLIs are not expected to produce logging output: they take in stdin and command line args, and output stdout and stderr. Our CLI does have at least one exception: we start a server with start dev. However, warnings and errors from short "transactional" commands should just be printed to stderr as plain natural language, without timestamps or other metadata.
One example of a current violation is
$ temporal operator namespace create default
time=2024-05-17T17:42:01.766 level=WARN msg="Passing the namespace as an argument is now deprecated; please switch to using -n instead"
