The "leader" has no choice after they win the current round but they do have a choice as to what to include in the winning block before they start hashing.
Maybe they act like all the other rational miners and optimize by mining fees.
Maybe they include no transactions and only take the miner reward.
Maybe they they don't like the Dutch so all their transactions are excluded.
It really doesn't matter as all y'all have been arguing over is what to call the
person who won the current round.
