And all the symptoms were practically identical. Tail icing doesn't make sense for one simple reason - it would be at its worst during the approach with all flaps fully extended, not the go-around.
You make a good point, but all the other theories make even less sense as we know the pilot said "Pull, Pull, Pull" and yet there was no sign that all that pulling did anything to stop the aircraft from violently nosing over.
Tailplane icing is very rare. I doubt we know everything there is to know about it.
If the tail did stall during the late stages of the go-around, this accident could be a game changer.
