--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
C++17 support in GCC 7.x is experimental and incomplete.
Following the release of GCC 7.5 the gcc-7 branch is now closed. Even if the
changes to std::variant were possible to backport from later releases, we
aren't going to make a GCC 7.6 release now anyway.
