A computer being able to control its own power is a relatively new thing. Systems of old had only "halt", and without a separate command, it was changed to power off once that functionality appeared in the hardware. For PCs, it was at the time of AT -> ATX. > I believe at least in some of RPM-based distributions /sbin/halt also > turns off computer.

On one hand, it follows the name of these commands. On the other, I can't quite fathom the purpose of that infinite loop. If someone for some weird reason wanted the final hang, you can kexec that or something -- it's a really odd case.
