 From the FSF's point of view, this is brand new code and, as such 
should, from day one be given the correct (C) and correct license.  To 
do otherwize would be confusing.

Think of this as part of a brand new port that you've never seen before. 
Even though the contributor might have a separate repository containing 
a very long history of changes, all that is irrelevant to the FSF.  From 
the FSF's point of view, the file is ``born'' the day someone 
contributes it.
