In the past I played a variant online that had no trading. The current trading aspect of BGA Catan is time consuming and often forces me to run out of time when I want to do a big move at the end of the game, as all my time is used up rejecting impossible trades.
Having a no trade option would speed up the game for those who want a quicker match.
