Both std::pmr::new_delete_resource and std::pmr::null_memory_resource return pointers to static-duration objects. It seems unspecified when the pointed-to objects are destroyed, so users can't reliably use these objects during destructions of their static-duration objects.

std::generic_category and std::system_category have the same issue, except that the referred-to objects may have different storage duration.

Should we specify in which case can these objects be used in the termination of a program?
