Yes, but GNU true does so much more! It supports --version, which tells you all about who wrote it and about the GPL and the FSF. It also supports --help, which explains true's command-line options (--version and --help). Then there is the i18n support, so that people from all over the world can learn about --help and --version. You just don't get all that with a minimalist ELF binary.
