Thank you for your reply.

How about some time before this DIP is fully in the language, a 
compiler flag is added that will produce warnings for when extern 
prototypes without explicit @safe/@trusted/@system are used? Or 
something like that. I have a good sense of when my own code uses 
extern(C), but not always other people's.
