We don't talk about Pun-Pun
I find the idea that dragon breath is ok because it's magical to be kind of odd. I mean, last I checked, we don't have shapechanging humanoids or sentient goo people in our world either, so if a dragonborn's physiology is magical, then so should a changeling or plasmoid's. Until we have some litmus test for what is or is not a supernatural ability, I'm inclined to say "if a real creature can't do it, then it must be magic".
