Adding native support for those colour models in the same manner as sRGB
wouldn't change that: Colours you specify via the "srgb" keyword are
immediately converted to linear RGB (presuming you're using
"assumed_gamma 1.0").


To change the blending behaviour, we wouldn't have to implement a
different syntax for specifying colours, but a different mode to
interpolate colour maps (see the `blend_mode` keyword). To add
custom-tailored blend modes for each and every colour model ever
designed would, in my opinion, be unreasonable -- my guess is that most
of those interpolation modes would only be ever used to render scenes
demonstrating that particular colour model.
