		*
		* The methods allow client apps to communicate what flags they care about, and receive back
		* current values for those flags. For stable flags, this is the finalized value until the device
		* restarts. For {@link DynamicFlag}s, this is the last known value, though it may change in the

		*
		* The response will contain a list of matching SyncableFlags, whose values are set to what the
		* value of the flags actually are. The client should update its internal state flag data to

		*
		* Generally speaking, if a flag that is passed in is new to the FeatureFlagsService, the
		* service will cache the passed-in value, and return it back out. If, however, a different
		* client has synced that flag with the service previously, FeatureFlagsService will return the
		* existing cached value, which may or may not be what the current client passed in. This allows
		* FeatureFlagsService to keep clients in agreement with one another.
