No, this is not yet the reason to expose transformations to clients.
You are only suggesting to make the protocol a huge deal more complex

That's not what I was suggesting. The compositor won't pick it's

Can we have a tool like 'xgamma' now?

If the hardware supports sRGB textures:
EGL: Use sRGB textures and present it as linear gamma
to shaders.

When rendering srgb_a in linear gamma, we can use sRGB hardwar

Actual rendering of window contents is not done by Wayland so it should
not effect this. However wayland and the shells do some compositing, and
gamma changes how any partially-transparent pixels work. In current
shells these are:

Currently most applications are blissfully unaware of the concept of
gamma which affects pretty much all rendering operations. Resizing,
alpha-blending, blurring, anti-aliasing, etc. are all operations that
should be done on physical or linear luminance values. However if we
