     // It seems misguided in our case, however, since we have an active health probing model
     // that can determine endpoint health more reliably. In particular because Service Fabric "Error" states does not necessarily mean
     // that the replica is unavailable, rather only that something in the cluster issued an "Error" report against it.
     // Skipping the replica here because we *suspect* it might be unavailable could lead to snowball cascading failures.
