Right, but how many people profile their systems printer, and have
a Fogra CMYK profile pop out the other end ? :-) ie., a Fogra profile
is a user supplied profile, selected in applications by the user.

A system device profile is a profile for a device connected to the system.
The user will profile the printer connected to their system and then
install the profile, so that when the application asks the CMM for
the profile associated with the system printer, it knows what to return.

In general users won't need to navigate to the system device profiles though.
They will select profile for other purposes (defining undefined input colorspaces,
selecting colorspaces to emulate), and then say "print it to my printer", expecting
that the printer driver will deal with the profile for the printer.
