I think it's a bit of a useless option, because it will not have any influence on the game.
Every player now has a contract for life. This doesn't have any influence on the costs.
If you have a limited contract, you are only getting higher costs for no reason.
Transferlist stays the same, the only thing that I can think of is: that more players will be available on the transferlist because people forget to sign another contract.
Plus it will be more difficult and will be a more specific managementgame, while I think that the developers are trying to keep it simple and more arcade.
