It will not be enough because std:;forward_list has n= o such member functions as push_back() and back used in the realization of = std::stack.

Instead of a single specialization, would it n= ot be better to just make size() only enabled for wrapped types which have = a size() using some enable_if logic?

In fact std::forwar= d_list has already all characteristics of a stack. There will be only one d= ifference compared with the primary class std::stack:  the specializat= ion will not contain member function size() because std::forward_list has n= o such member.
 
What will you say?
