The `--internal-topics` option is especially useful when there are prefix conflicts between applications, e.g. "app" and "app-v2". In this case, if we want to reset "app", the reset tool's default behaviour will delete both the internal topics of "app" and "app-v2" (since both are prefixed by "app-"). With the `--internal-topics` option, we can provide internal topic names for "app" and delete the internal topics for "app" without deleting the internal topics for "app-v2".
