> When you install Go, it does just that, to some approximation; it will try to fetch from the module proxy first and fall back after that fails.

Go is telling you that your VCS has a deficiency, without saying it out loud.

That proxy should be your own repo... but git sub modules, sub trees, sub directories are non starters for 99 percent of cases...

Git is an amazing tool, and if you want to manage your development like the linux kernel its dam near perfect. Most orgs dont work that way, and the tools and machinations that we have built around these shortcomings are rather burdensome.

I long for google to productize piper for the rest of us.
