Are you sure it's the variator? It's just I wouldn't really describe it as a rattle, more of a diesely clattery noise.
If it is the variator though, that 'rattle' and a loss of performance IS it failing. By all accounts it doesn't get any worse than that, and it doesn't threaten to damage anything else, it's just whether you can put up with what it's currently doing.
