Yes. Or, to be sure we're talking about the same thing, what I'm saying is:

For any C++ standard library container class template 'C  that has an
'Allocator' template parameter type and whose constructor accepts an
instance of 'Allocator': i.e.

template<..., class Allocator>
class C {
    ...
public:
    C(..., const Allocator& alloc = Allocator());
    ...
};

Then the implementation of that container 'C' must use an instance of
'std::allocator_traits<Allocator>::rebind_alloc<unspecified>' that
compares equal to 'alloc' (i.e. a rebound copy of 'alloc'), for all
dynamic allocation that it does.

For "supports allocators" to mean anything less than this, is just not useful.
