Should C linkage (aka "extern (C)") be the default when using "betterC"?

Basically pointless. The linkage of internal symbols has almost 
no relevance to a projects usability from C. You'd also be 
throwing away anything that requires name mangling, for zero real 
benefit.

If you want to expose a symbol to C then use extern(C). This is 
not hard to do.
