My thoughts are that profiling in negative scanning workflows is doing little 
more than providing a rough guide for the interpretative edits which are always 

A scanner cannot get RGB values from negative that have any dependable 
relationship with the colorimetry of the original scene. That's the whole point 
of using negative -- massive exposure range recorded using minimal density 

And given that the scanned values don't correspond to the colorimetry of the 
final print either, I can't see profiling playing anything other than a very 
minor part in the image processing.
