As usual: citation needed. That leads to a contructive dialog.
Marginalisation is no good style.

You can not be serious about this.

CPD runs as a user process. Thus the user relation is first class. While 
xxxtoraster is a server side process running as user lp. How might lp 
know, which ICC profile is the actual one and from which user? On 
which mechanism does the scheme rely on? It was brought up several 
times. I never read a convincing answere for that question.
