std::uncaught_exception should be deprecated in C++17

Current libstdc++ source:

_GLIBCXX17_DEPRECATED
  bool uncaught_exception() _GLIBCXX_USE_NOEXCEPT __attribute__ ((__pure__));

Current libc++ source:

_LIBCPP_FUNC_VIS bool uncaught_exception() _NOEXCEPT;

There is a good reason why std::uncaught_exception() became obsoleted as soon
as the alternative appeared:
