Well. That's the part of CMFSetup I still don't understand. How is "the 
code which sets up the site" created? Separating configuration from code 
is the Right Thing. But how does that help to resolve dependencies 
between products and the configurations they require?

Just an example: The "default" profile doesn't include CMFCalendar 
configuration. How would we use CMFSetup for a site that needs calendar 
features? Do we download a "CMF_with_calendar" profile? Or do we combine 
a "default" profile with a "calendar_support" profile? And if yes: How?
