We should be able to play in older worlds with older add-ons

Currently in the marketplace if you download an older world and open it insted of automatically updating the world would actually open in that older version so what if when opening any world from and older version instead of automatically updating the world would give an option to update OR to keep the older version and open the world in that old version This can be really helpful for add-on creatures and consomers because now if the add-on creater didn't update their add-on yet the players can still play it in it's older version (this is already a feature with worlds in the marketplace but if it was possible to do this with add-on's that don't have a world with them we will be able to run older add-ons much easier and also be able to run worlds from older version much easier
