So what? People are experimenting with novel tools for review and publication. These restrictions are dumb, people can just ignore reviews and position papers if they start proving to be less useful, and the good ones will eventually spread through word of mouth, just like arxiv has always worked.
ArXiv has always had a moderation step. The moderators are unable to keep up with the volume of submissions. Accepting these reviews without moderation would be a change to current process, not "just like arXiv has always worked"
