Use library completely without std::allocator (operator new)

[Feierdeifel]

Hi,
Is it possible to use the library completely without a call to new operator.
I set the basic json to my containers and allocator.

namespace dynalloc {
using allocator = CountingAllocator<T>;  //Custom allocator
using string = std::basic_string<char, std::char_traits<char>, allocator<char>>;

template <typename Key, typename Tp, typename... Args>
using map = std::map<Key, Tp, Args...>;

template <typename Tp, typename _Alloc = allocator<Tp>>
using vector = std::vector<Tp, _Alloc>;
...

using JsonMb = nlohmann::basic_json<dynalloc::map,
                                    dynalloc::vector,
                                    dynalloc::string,
                                    bool,
                                    std::int64_t,
                                    std::uint64_t,
                                    double,
                                    dynalloc::allocator>;

This works but I still get calls to new() because the lib uses vector<> or make_shared<> in the code.
Basically I do nothing special with the lib. Just creating some json strings and dumping it to other functions

Because I am not able to check what happens in detail I wanted to ask the community if this is possible.
