Extra ratios cost real money. They also add weight - more than just the extra ratios would suggest because longer gear shafts deflect more so have to be made stronger or supported better - and some friction. For them to be specified there must be a tangible benefit.

As pointed out by aardvarcus, having more gears is not so absolutely right if their ratio is too compromised, either for performance or fuel-economy.
