can we use Qt-style instead of native file dialog under Windows?

In GUI/View/Widget/AppConfig.cpp, we have

bool AppConfig::useNativeFileDialog() const
{
#ifdef _WIN32
    return true;
#else
    return false;
#endif
}

Is there a strong reason for that? If yes, explain in a code comment. If no, let's use Qt style everywhere.
