That is correctly described and expected behaviour as developers said.

We discussed that with Wayland people and the last spec revision was 
adapted to meet their concerns. So the transition from X Color 
Management to W(ayland) Color Management should be relativele smooth.

What other substantial proposals or discussions do you have in mind?
As far as I can see there was no publically discussed *competing* concept 
of substance ever brought to the attention of the graphics community.
We only have read some nebulous and non technical statements on the typical 
level of marketing.

OpenICC [1] is the fd.o place to discuss such CM stuff or at least the 
Xorg email list. In both I am active. I will surely continue to present 
and discuss the idea with users and developers in various events.

kind regards
