It might be worth noting that while all this is wonderfully idealistic, there 
are a LOT of existing graphics files in all kinds of formats that people will 
use and apply formats to. Programs that do or will use CMS or libraries that 
support CMS need to handle these just as well as the rest. You simply cannot 
exclude certain formats from being used by whatever user base, and even if 
they were to convert them to a supporting format, you then must give them the 
ability to supply a profile, assuming they even have an idea what it 
originated from.
