Is there really any point to jtag/rgh for 360s anymore?

I found a falcon 360 on the side of a road by someones trash a while ago, with no power supply. I recently used an atx power supply to try and see if I could fix it, cause I was sure it wouldn't be functioning. To my surprise it started up ran great. So what would be the main reason to do this today.

Modding chip. Let's you run pretty much whatever you want.
