    For Traffic Director, the number of backends per backend
    group (the subset size) is based on the `subset_size`
    parameter.

    For Internal HTTP(S) load balancing, the number of backends
    per backend group (the subset size) is dynamically adjusted
    in two cases:

    - As the number of proxy instances participating in Internal
      HTTP(S) load balancing increases, the subset size
      decreases.
    - When the total number of backends in a network exceeds the
      capacity of a single proxy instance, subset sizes are
      reduced automatically for each service that has backend
      subsetting enabled.
NONE (2402104):
    No Subsetting.

    Clients may open connections and send traffic to
    all backends of this backend service. This can
    lead to performance issues if there is
    substantial imbalance in the count of clients
    and backends.
