It will also change the process from the perspective of an author. If you are not fully sure about the impact of your publication, you might start submitting it to the journal with the highest possible impact. And, after a rejection, continue submitting to the next best journal, until acceptance. The new process by eLife would hence massively cut the workload on authors, besides editors and reviewers.
