The current implementation allows creating compound hashed index if featureCompatibility.isVersionInitialized() evaluates to false. This might cause issues if FeatureCompatibilityVersion object ever gets uninitialized.
We need to change this code to

const auto isFeatureDisabled =
                (!featureCompatibility.isVersionInitialized() || featureCompatibility.getVersion() <   ServerGlobalParams::FeatureCompatibility::Version::kFullyUpgradedTo44);
