That is not possible. End users install Oyranos and gnome automatically as 
a hard dependency of various packages.

My point is not about introducing more patches to CUPS. The profile 
selection path must be well defined or we can stop in colour management 
and obtain chaos. The actual hack is not a open API. It is a pain for 
users to check various GUIs if their profile selection is not side 
stepped or to trace bugs in such a environment.

I am not sure if that is the right level for the above problem. Profile 
selection and profile matching are quite different parts in the system. 
Anyway, cooperation on standards is a good thing.
