YES! -- We should look forward and not only glorify the good old FOURCC 
naming and legacy pixel data arrangements.

The more verbose and systematically ordered sets of pixel format 
definitions used by those newer GPU processing oriented APIs (e.g. the 
vulkan one: https://docs.vulkan.org/spec/latest/chapters/formats.html) 
are very useful in practice. Supporting them makes code much more 
compatible and future-proof.
