Thank you for your explanations. I caught the main idea. So for SQL programming it's possible to introduce 'local IsNull':

template<typename T>
bool IsNullSql(const T& t)
{
  return IsNull(t);
}

bool IsNullSql(const String& s)
{
  return s.IsEmpty();
}

But it really is not only about SQL. I agree that it is a little bit controversial, we know it, but the convention is really quite practical.
