      Server parameters can be made conditional on either a minimum FCV or a feature flag in the IDL definitions, as follows:

          spTestNeedsFeatureFlagToaster:
      description: "Server Parameter gated on featureFlagToaster"
      set_at: runtime
      cpp_varname: gSPTestFeatureFlagToaster
      cpp_vartype: bool
      condition:
        feature_flag: gFeatureFlagToaster
        min_fcv: 8.1

      This is currently implemented as ServerParameter acquiring a global FCV snapshot and using this as the basis for checking is the minimum FCV or feature flag condition is fulfilled..

      This logic should be adapted to also take Operation FCV into account.
