Comment (by Alexander Karzhenkov <karzhenkov@…>):

 It's needed. Just try slightly modified test:
 {{{
 #define BOOST_THREAD_VERSION 4

 #include <boost/thread/future.hpp>

 void func(int) { }

 int main()
 {
         boost::packaged_task<void(int)> task{func};

         task(0);        // ok

         int x = 0;
         task(x);        // compile error: can't bind to rvalue reference
 }
 }}}
