Wouldn'tgo build be able to automatically retrieve these?

[maysunfaisal]

Good question, I tried finding this exact verbage for go build on docs but didnt find any https://go.dev/doc/tutorial/compile-install

I tried various random posts and stackoverflow but didnt really find any info about it! 🤔

[maysunfaisal]

Honestly I am down to not merging this because I had the same notion before opening this PR.

[maysunfaisal]

Closing this, as I echo what John mentioned in the comment, I dont think we need this.
