This brings the CMM into the applications and the rending backend. For
what benefit? How does device link profile avoid the presence of a CMM
down the path?
As well, when a user wants to be able to select globaly a certain CMM and
his application opts in for colour management, as should be the default,
then there will be CMM specifics down the path in any case.
