It is, but far less dangerous than --unmerge. depclean will only remove packages when portage /thinks/ it is safe. unmerge will always remove them, even if it breaks the system. Nevertheless, like Dale said, you should be careful with depclean and use -a or -p with it. But if depclean makes an error, there is usually something else wrong with your system.
