I think the idea is for private-scope / local to not be seen from extensions in other files. I am not sure how that works for same file extensions.

Yes. just like local.

In essence there are two ideas floating around in my head:
1) give the new local / private-scope a unique name like 'secret' or 'protected' and keep everything else the same.  

2) redefine this new local / private-scope as just 'private', 
private-file becomes 'internal' , we find a new name for private-module like 'external' and we keep public as is. 

I'm am now leaning towards number 2. 

External (default)
