I think so.

In (gnu packages)?

The only thing to keep in mind is that (guix build gnu-build-system) is
used by packages in commencement.scm, which run on Guile 2.0; thus
gnu-build-system.scm cannot rely on features that appeared in Guile 3.0.
However, for ant-build-system.scm it’s fine to rely on those.
