The current draft has make_pair() in 19.4 [pairs]/16 and make_tuple() in 18.104.22.168 [tuple.creation]. make_tuple() detects the presence of reference_wrapper<X> arguments and "unwraps" the reference in such cases. make_pair() would OTOH create a reference_wrapper<X> member. I suggest that the two functions are made to behave similar in this respect to minimize confusion.
In 19.2 [utility] change the synopsis for make_pair() to read
template <class T1, class T2> pair<
typename decay<T1>::type, typename decay<T2>::type> make_pair(T1&&, T2&&);
In 19.4 [pairs]/16 change the declaration to match the above synopsis. Then change the 19.4 [pairs]/17 to:
typename decay<T1>::type, typename decay<T2>::type>(forward<T1>(x),forward<T2>(y))
