Investigate if we can remove the offset in Mimir aggregation sets
In #2486 (closed) we've added a 30s delay to all of our recording rules in Thanos & Prometheus to account for metrics that might not have been received yet.
Mimir does this by default: https://github.com/grafana/mimir/blob/b69b4f481f2e2cd694ea5e8959b21d12ce8e38fb/docs/sources/mimir/configure/configuration-parameters/index.md?plain=1#L3270-L3273, and Prometheus is considering the same https://github.com/prometheus/prometheus/issues/11807.
This means that in Mimir, we can potentially get rid of the offsets we've added to our recording rules.
