Thanks, but as we already tried to explain, instantiating, thus adding many exported symbols, is post 4.9 material, can't be committed until we branch. Please make sure to have in a separate patch or multiple patches the correctness fixes and maybe anything unrelated to instantiation which you consider stable and independently useful.

Please make sure Francois knows about that...
