Is Keyblade Master title necessary?

[vlad segundo 0]

Have in mind, I havent played KH3 yet T.T 
But is that title really necessary? From what i read, it only is a title and you are allowed to go on to other worlds or train other keyblade wielders... you can get those special powers without being a keyblade master, like sora did.

The only perk in being a Master is getting insider information and not being being left out on matters.
