I don't think you quite understand what optional means.After finishing everything there i can 100% tell you this is not optional.
1. There is enemies that give you exp and if we see in the events before and the events that are going to come exp means a lot so for those that do the dungeon this is a plus for those who do not do it this is a minus.
2. There are items that boost the characters and maybe they will "play " a role in some future events.
3. The throne boosts the base +1 and the numbers of the base were used in events.
This is a must do not optional
You don't need to do that dungeon to finish the game. Sure it gives a bonus, optional dungeons usually do in most RPG's, but you can play the game just fine without ever doing it.
RPG's have 2 kinds of dungeons, mandatory which are needed to progress the game and optional which aren't needed to progress the game.
Having bonus items doesn't make them any less optional.
