Why no songcast on Naim streamers?

Having just sold my second hand Linn Sneaky (could not live with it's sound quality which seemed to me as being lifeless and dull), I was about the purchase a naim streamer, but I realised that I really do miss the songcast feature on Linn DS which allows me to play youtube music videos.

Since it is open standards anyway, why does Naim not enable this feature, or built one itself.

it's really a fantastic feature, and if enable, will give Linn DS a very hard time.

Airfoil has latency issues, and is really a no go for me. After using songcast, which is really brilliant, any other solution seems very mediocre.

Airplay also has major latency issues, a complete non starter.
