Punctuation!!!

A few minutes ago I was typing 「おめでとうございます」, and the Windows Japanese IME asked me which of these I meant:

おめでとうございます！
おめでとうございます！！
or
おめでとうございます！！！

I don't know whether it's assessing my enthusiasm or my developmental age. Maybe the next generation of emoji will ask you to input smile intensity, on a scale or by degree.
