If I understand correctly this touches only the new C++17 members and in 
any case, a recent commit by Jon disabled the extern template strings in 
C++17 mode, thus there are no ABI-related risks in that mode.

Patch looks good to me. I'll get to your other contributions later today.

Thanks,
Paolo.
