Do we still need to populate 'extern'? Can we get rid of this redundancy?

In my opinion, while you're right that it isn't necessary because all
functions (unlike variables) are implied to be extern, the use of
extern to indicate functions that are exported/intended to be part of
the API is a good idea.
