I fail to see how it changes things in a fundamental way. Having your name on a paper is supposed to mean that you contributed to the results of that paper. This is how you build up your reputation: you publish lots of relevant results.
This is only possible if you continue to work and publish, which in turn makes you a more sought after partner for collaboration. In the same vein, if your contributions are consistently minimal, then you will be less sought after which will lower your frequency of publication. In essence, the current system already correlates rewards with the quality of one's contributions.
Thus, the proposed changes do not affect how one garners reputation. Instead, I think the subtext is that the current body of research papers could be significantly improved, but isn't because there is no system in place to revise them in a distributed manner.
