The proposed resolution of n3157 would satisfy this request.

[ Resolution proposed by ballot comment: ]

Review every class and class template in the library. If noexcept move constructor/assignment operators can be implicitly declared, then they should be implicitly declared, or explicitly defaulted. Otherwise, a move constructor/move assignment operator with a noexcept exception specification should be provided.

Addresses GB-61

All library types should have non-throwing move constructors and move-assignment operators unless wrapping a type with a potentially throwing move operation. When such a type is a class-template, these operations should have a conditional noexcept specification.

There are many other places where a noexcept specification may be considered, but the move operations are a special case that must be called out, to effectively support the move_if_noexcept function template.
