For a long time, the date for players delisting themselves was after the closing date for ND nomination forms. Their only option was the PSD. The AFL eventually changed the list lodgement dates, and players who are forced to wait until LL2 to delist themselves were/are now able to nominate for the ND and the PSD.Curious about the second sentence. What has been removed?
The whole reason for the PSD was to act as a circuit breaker, allowing players to find new homes while still specifying contractual terms, if their clubs refused to release them or failed to trade them as requested. The ND now offers this same ability to the players - so the only reason for the PSD's existence has effectively been removed.
