This is probably because of the circular dependency between modules, and inherit across modules will cause problems also see https://issues.guix.gnu.org/77653#11 |I forgot the most important bit: inheritance cannot happen between |different modules, as it uses direct (non-delayed nor thunked) |references to the package objects and would introduce module circular |dependencies, which are surprising and not fun to hunt down.
