I don’t follow. Why is the code change important?

Why not just use the go module cache? Seems like a much cleaner solution with very little overhead.

The idea of making a change and rebuilding is about proving that the build process does not require a network connection and that you have properly resolved the depencenies on that machine.

The change is unnecessary. You can just rebuild.

If you’ve built once using the standard go module functionality then you will be able to rebuild as long as you don’t pull in more dependencies. Naturally you can move the cache around.
