If the headline was much better quality, maybe, but it's not immediately clear to me that this is in any way better than just using higher quality/size JPEG.
I agree, half the size is for most people irrelevant. The article mentions the quality improvement you wanted but did not make it in the summery. Upto 14bits per channel could be a major plus when implemented natively in a DLSR.
Even then it first need to be widely supported before it is used by many, it needs to be used by many before it will be widely supported.
