<variant>: Should we treat P0608R3 as a DR against C++17? #4412
Description
WG21-P0608R3 was intentedly not treated as DR by MSVC STL (#1629 (comment)).
However, the author of P0608R3 (@zhihaoy) applied those changes to libc++ in C++17 mode (LLVM-D44865), and so did libstdc++ (gcc-mirror/gcc@d069df0). So it's arguably that P0608R3 should be treated as DR even though it's not so treated officially.
There's at least one user even thinking MSVC STL is buggy (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113007#c7).
