This seems unnecessary. Optional means that you do not need to kill the boss in order to complete the game. If you do not meet their criteria, then you don't have to fight them in order to win. Neither of these bosses NEED to be killed to win.

Also, there is only two examples of these. Creating a new listing for only two things seems pointless.
