The fact that this file format doesn't enclose the AdobeRGB vs sRGB information is a deal breaker.

A lot of computer vision research datasets uses a similar file format - so I can see its use there. But things like movie creation, publishing, etc will probably never adopt this.

Indeed. I'll reiterate - it's vital that images have a known color space. Even if OP just states that farbfield is sRGB, it'll help. Otherwise, you've only got a 3D matrix, rather than an image.
