Let me explain my reasoning. Suppose I made an .ptar archive today, put it on a USB stick, threw that in a vault and forgot about it. Ten years down the road I want to restore that archive. But the .ptar file alone is useless without the plakar tool. So I have to install plakar first. Ideally plakar should sit on that USB stick, right next to the archive, ready to be installed. But plakar is dependent on Go, so I have to hunt Go first. And who knows what the state of Go will be ten years down the road. The .ptar file that I made today may end up unusable ten years later, because Go evolved in some unpredictable way.
