We're about to hide config functions that implicitly depend on `the_repository` behind the `USE_THE_REPOSITORY_VARIABLE` macro. This will uncover a bunch of dependents that transitively relied on the global variable, but didn't define the macro yet. Adapt them such that we define the macro to prepare for this change.
