> The AutoScaling "cores" preference works by counting the core names that are retrievable via the metrics API. 99% of the time, that's fine but it does not count unloaded transient cores that are also tracked by the CoreContainer, which I think should be counted as well. Most users don't have such cores so it won't affect them.
> Furthermore, instead of counting them by asking the metrics API to return each loaded core name, it should use the {{CONTAINER.cores}} prefix set of counters.
