CFP has been around a while, like 8 years at this point. CFP2 and CFP4 are significantly smaller have accordingly lower 
power budgets and do not include the DSP on board (the linecard for cfp/2/4/8 differs significantly respecting level of 
integration components and so forth and also port count).

Apart from the resulting low port density per card, which makes them unsuitable for a number applications they're 
mature products at this point.
