Because they are the simplest and cheapest way to get the desired results?
I don't care how easy it was to add the "-q" option, it was a waste of the
programmer's time. A shell program using pipes could have been written in
seconds, solving the problem without messing around with "who".
There seems to be a pervasive delusion that the only two ways things can
be done are (a) add every conceivable option to the C program or (b) force
the user to type long sequences using pipes. The correct approach, when
such functionality is often used, is to package it up in a system-supplied
shell file.
