LWG 2132 constrained std::function's constructor and assignment operator from callable objects for C++14. The constructors of std::experimental::function isn't separately specified in the fundamentals TS and so inherited the constraints from C++14, but the assignment operator is separately specified and presumably needs to be constrained.
