No there isn't. The presence of something in a TS does not imply it has been proposed for C++17 (or any later standard). Even if it had been proposed, it's not part of the C++17 draft, which is supposed to be feature-complete. IIRC the only pieces of the Library Fundamentals TS v2 proposed for C++17 were gcd and lcm, everything else that made it into C++17 had been in Library Fundamentals TS v1 for some time and wasn't new in v2. Most of the new stuff in v2 needs more time to bake.
