I have a lib module planned to be used across projects. It will depend on many other modules.
But not all the projects will use functions provided by lib. I'm wondering if a project only depends on b/func B provided by lib, will it pack all the unused modules during project's build?
I understand go's smallest build unit is a pkg. In such case will ext-depency A module and ext-depency N module pack it into my project module binary?
How can I test this?

No.

No idea what you are asking.

Inspect the generated binary. (No, don't do that).
Honestly, this is a 100% non problem. Nothing to see or worry here. Forget all this. The generated binary contains what is necessary and nothing else. Unused stuff is stripped during linking.
