Indeed. In my experience and other researchers I know, often rival groups will try to block your research from getting published in Nature or Science by asking for unreasonable follow-up experiments. It's sadly very political. Hopefully this will improve things.
I personally know the current Nature chief editor and she totally agrees with my points above. In contrast, I have always found math & CS journal reviews way more fair and rigorous.
