Almost, but not quite. Certainly the "benefit and the welfare of the many" is the key. My own view is that limiting race distance according to age does not necessarily mean holding back young athletes. There are ways of progressing development without increasing race distance: improve running technique, running efficiency and, most importantly, speed. It's better that a talented runner smashes course records over her/his allotted distance than simply competes over longer distances with athletes who are, in almost every way, more mature.
That's not to stop them training over further, and with older athletes, if that is what the coach deems appropriate.
