I've typically used pdsh https://github.com/chaos/pdsh for these types of commands, and I don't think they have any such safety options. The only protection is to be wracked with fear whenever you type pdsh. Obviously this fear wanes with use, and eventually you don't think about a command for long enough before you do it and hit enter on a regrettable one.
