Exactly. Most of the time “build-side” module are not loaded in the
Guile process that uses ‘with-imported-modules’.
It’s a bit of hack but it’s necessary. Guile could provide this
functionality, but (guix modules) bakes in a few assumptions, notably
that all the source files start with ‘define-module’.
