It would be convenient if Instance had some optional components for controlling state which is typically expected to be global to the instance. This includes the time of day, whether or not time is paused (doDaylightCycle), The world border for the instance, the weather (raining or thundering), etc.

My current thinking is that we can have the following components:

• TimeOfDay
• Weather
• WorldBorder

Might be more convenient to make these components smaller for the purpose of change detection. Not sure.
