 arguments functionality, introduced in 0.14.0, is used.

+------
+
+Getblocktemplate sets the segwit version bit even when the downstream
+client has not been updated to include the segwit commitment.  Ability
+to enforce the rule is the only required criteria for safe activation,
+but previously signaling was only requested if the miner could include
+transactions in order to avoid a potential outcome where segwit would
+activate at a time when no segwit transactions could be included.
+Since many miners are now including the segwit commitment this concern
+no longer applies.
