Maps and Commands

I would really like to be able to access to the Map data such as:

• Coordinate
• Zoom Level
• Markers list
• type ? (for example, is it a treasure map, then the outline should be draw even if the map have not be explore)

I can see few reasons why this could be useful:

• When a player die we could bury  its inventory in a chest nearby. And all  the players could have the chance to loot a map with this treasure marked on the map
• We could add custom marker to a map via command to create quest
• We could do an Atlas (https://feedback.minecraft.net/hc/en-us/community/posts/360032469172-Books-of-maps-Atlas-) in a data pack
