Not backwards compatible. We just add it to that nice cupboard "great advanced image formats we will forget about".

Society doesn't need a new image format. I'd wager to say not any new multimedia format. Big corporate entites do, and have churning them out at a steady pace.

Look at poor webp - a format pushed by the largest industry players - and the abysmal everyday use it gets, and the hate it generates.

There's a big issue that all old popular image formats are 8-bits. 10-bits or even 12-bits would help a lot with storing more information and maintaining editability.

If adding more bits to an image format, please make it 'n bit'. Ie. the file could be 8 bit, it could be 10, it could be 12, it could be 60 bit!

Whilst we're at it, please get rid of RGB and make it N channels too.

Libraries can choose to render that into a 3 channel, 8 bit buffer for legacy applications - but the data will be there for CMYK or HDR, or depth maps, or transparency, or focus stacking, or any other future feature!
