If yes, it might be worth it to get rid of export as a keyword out right 
in a DIP (as it introduces the possibility of linker errors that would 
otherwise not need to exist).

I fully agree; it's still very useful with `-fvisibility=hidden` 
to only export what you really want (e.g., in order to quite 
likely shrink the final size of executables and plugin libs 
considerably) without the blunt export-everything method (which 
is nice for libraries like druntime and Phobos).

Please, no. -fvisibility=public doesn't work in all cases in our 
experience.

And there is also DLL export limit on Windows which 65k symbols, 
yay.
