I'd presume these things run at mA of power? Why would there be concerns to it getting hot?

  Because kids do things like connecting VCC and ground, or drawing too much power from microcontroller pins, etc. (I guess)

    Voltage regulators usually have a short circuit protection circuit though.

      They don't have polarity protection.

      That's a good point. However, many regulators get hot with high loads. Also, the short circuit projection of some regulators is to burn out. Given all these problems and the relative carelessness of kids, I can see why they would dig through spec sheets and would measure temperature under various conditions.
