Exactly!!!!   That's what Eric did when he wrote more(ucb) -  he added to Unix.   The funny part was that USG thought more(ucb) was a good idea and then wrote their own, pg(att); which was just as arrogant as the info behavior from the Gnu folks!!!   Later, Less(internet) replaced more, but only as a superset, building on the foundation and eventually USB chose to ship more also as so many people wanted it.

As I said yesterday, standing on the shoulders, not on their toes.
