Warden Throws Lit TNT At You

Wardens have a ton of health, seemingly as much as the Ender Dragon without her weakness to headshots. However, based on my estimations, it'd only take three pieces of TNT to take out a Warden, and, with some practice, it would be fairly easy to quickly build a noisemaker right next to a sufficent amount of TNT and shoot it with a Flame bow while the Warden is distracted. That probably makes it too easy to kill the Warden. So, when the Warden detects a lit piece of TNT, it should realise the hissing sound is bad news, immediately make a beeline to it at maximum speed, pick it up and throw it away, preferrably at the last heard location of the player. That would be a very strong deterrant to TNT-based shenannagins. Additionally, you could probably make an interesting farm out of it somehow.
