That's not a user-friendly to do. I disagree. (1) Some systems use per-user groups and create all files group-writeable by default, i.e., they set the umask to 002. If you want to be user-friendly, you should respect this setting, so the permissions in the tar archives you distribute should be 666. (2) People extracting random archives as root with preserving permissions (and owners) are relying on *ALL* archive creators using what they suppose are the right permissions, which is at least simple-minded, if not completely silly. If you want to help such users, you should do so by helping them understand they do a wrong thing and not by hiding the problem in a single specific case.
