Right. You can get both real time and delayed stock quotes via a getStockQuote interface, which is better than requiring separate interfaces for each type of quote (getRealtimeStockQuote(), getDelayedStockQuote).
Generic semantics just take this practice - which improves reusability and reduces coupling - to an extreme. Seems like a good idea to me! And think how popular and widespread a protocol with these kinds of generic semantics would be! 8-)
