This requires the custom activation handler to deal with all possible activation scenarios. In certain kinds of tests that might be an overkill. It would be nice to have a way for the custom handler to return a magic value signifying that it cannot handle that specific activation and the default activation procedure should just continue, something like:

        if (winrt_activation_handler)
        {
            if (auto hr = winrt_activation_handler(*(void**)(&name), guid_of<Interface>(), result);
                hr != E_NOTIMPL) {
                    return hr;
                }
        }
        ...

I agree - I've had need for this flexibility myself
