I am an editor here, and the experiment looks to be interesting one... Consent from me too in this one... :)
The Paperbark Maple tree does not give any of those crafting bushels as you can also see on that list...
The only trees that give the Maple Syrup bushels are mentioned here... you will also find reference to other similar bushels:

In my opinion, stage 1 stuff is a BIG NO for the Wiki... No matter what...
Stage 2 also should be an exception if really really necessary to be added. Else, that also has to be avoided completely.
Stage 3 is what the Wiki has to concentrate on... there are a lot of items that still need info to be filled, and pages to be created for... They are to be given higher priority rather than making new pages for the first 2 stages of unreleased content...
Just for info, the items in Farmville can be classified into 3 stages based on their release state...
Stage 1: The images are created for them, and made available in their links database... They can either be released or abandoned anytime... Just because there are links does not mean that the item will be released.
Stage 2: They code the above into the actual game, which means that they can be available to the players via one means or the other... once coded, they don't usually remove such items from the game... But this stage does not count for the final release unless it becomes accessible to all the players without any special means...
Stage 3: The actual release, like when the item hits the market, or is a prize for something, etc... Only when they are accessible to the general public as a whole do the items fall under this category...
