Busybox is the forefront example of this in my mind. Busybox is a single binary that provides a ton of POSIX utilities (including sh, awk, ls, cp, nc, rm, gzip, and about 300 other common ones), and these can be invoked with `busybox $command`, or a symlink may be made from the command name to the `busybox` binary to automatically do the same. Many embedded Linux systems just use busybox and a ton of symlinks to act as the majority of the userland.
GNU does it their way, and Busybox does their own way too. Both have valid reasons for how things are set up. For users friendlinesr it's important then that they are as consistent as possible with it.
