Late night, odd choice of words.

The new API is capable of tuning the old and new products. For 
application developers it's not mandatory to move all of your tuning 
code to the new API just to support all of your current DVB products.

The S2 API support is written to support every current and new DVB card 
we're likely to see over the next 10 years, it's flexible... I'm simply 
saying that application developers can slowly migrate their code to it 
... you don't have to move all of your tuning code to the new API in one go.
