I think these are more like the basic rules of the game, rather than an official league rulebook. Like any other sport, additional rules would be needed for organized play, and those could vary from league to league. For example, no one will eject me from the court if I commit too many fouls during a pickup game of basketball at the park, but the NBA, NCAA, FIBA, etc. each have their own rules regarding fouls and their associated penalties. League rules also evolve over time, sometimes in response to rule abuse. So I wouldn't hold it against the game if the first iteration of the rules don't account for every aspect of competitive play. What's more important is whether the game is actually fun or not, and then leagues can evolve from there.
