Crafting Option to Fill Previously Explored Areas of a Map

I'd like to suggest a new map feature where, if you place an activated map into a Cartography Table or Crafting Table and add another resource (ink, for example), the map will automatically fill parts that have been previously loaded by players, removing the need to manually explore a map in areas already discovered by you/other players.

I believe this is a good suggestion for the game because this system is unobtrusive to the original map making formula. This system still incentives a player to explore new areas if they hope to complete a full map, it merely cuts down on the amount of time they would often have to perform re-exploring areas they have already discovered. Also, by requiring another step after creating maps like usual, this feature can simply be added onto the preexisting system without changing how it once worked. A player is rewarded for taking an extra step/spending extra resources in the mapmaking process to cut down on time walking where they've already been. I believe this system is also somewhat balanced as it requires a material cost in order to activate, meaning the devs could make this more or less expensive depending upon how powerful they believe this ability is to perform.

Please let me know if anyone has any suggestions or concerns regarding this feature. I'd love to hear people's feedback on it!
