Well in my eyes it does address module abandonment and disputed functionality quite well -- it turns them into a technical problem, with a technical solution -- change the authority.
Maybe you're too immune to the current situation. Now users have to pick between modules of identical APIs, rather than identical modules with different authorities. I'm probably going to end of forking POE within the next month. I'm not sure what I'm going to call it, but I'm sure it will confuse people more than seeing POE<cpan:rcaputo> and POE<cpan:ecarroll>
