As one of my directs pointed out, it also reduces the "blast radius" for any mistakes around metrics. If I mess up and send orders of magnitude too many metrics to Prometheus, the worst case is that I'll lose my own metrics since it's only my own instance. The pull nature of Prometheus also helps here. But with something like Graphite, I can accidentally overload the StatsD relays and ruin everyone's metrics, which is bad.
