Okay, but do the commands really have to be case sensitive? What's the difference between "scoreboard objectives" and "Scoreboard ObJectIves"? Do we really need to write out "creative", "survival", "adventure", and "spectator"? Do we really need all those specifics in the execute command? Do we really need a complete redo of Entity selectors? I could go on.
My motto on this forum is that simpler is better. We don't need longer command names. We don't need all these extra keywords and syntaxes. It will just make it harder to develop these commands.
I don't know how those specific changes affect the game so I can't tell if they are really necessary. All I know is that they are changing everything now in hope of not having to change any of it in the future.
