Using -### is insufficient to discover the entire set of frontend jobs needed to satisfy a given incremental compilation session because of the presence of additional waves of recompilation. More concretely, any additional compilation jobs whose queueing behavior depends on the set of jobs reported by -### are, by definition, hidden from -###. Note that it is also *not* possible to run the incremental build to a fixpoint by iteratively executing said frontend jobs and re-running the driver with -### because the build record is never updated to account for the jobs executed by an external system.
