About cloning, the core of the issue is not Guile but libgit2.  Guix
relies on guile-git which is just libgit2.  And sadly, libgit2 does not
support shallow clone or depth fetch option.  See libgit2 issue#3058.

If I read correctly, Go relies on plain Git, instead.

Therefore, sadly we cannot do better than full Git repository clone.

It would be difficult switch from libgit2 to plain Git; as discussed in
this thread [2].
