Its not relevant how a device is connected. The key is if users want to 
control how to do things. And certainly a important group wants control 
and in a convenient manner.

We want not only to hope, we want to control.

Thats a artificial limit. The trend is that more and more devices are 
networked. Colour management has simply to account for that.

The typical use case are healthy people in office running computers in one 
of the major languages and need no colour at all. If you want to 
concentrate on this user group, then strip any accessibility features and 
most languages from fedora and you are done. I am sure it will economise 
much of the fork on RedHat. Needless for you to talk about colour.
