Hi Haggardlyforte, 

I've gone ahead and reverted this change in https://www.openstreetmap.org/changeset/162441660 and wanted to let you know why.

The existing features that you added "golf=fairway" to are part of something called "multipolygons". They combine things like fairways and greens together to indicate that everything that isn't a green/bunker/etc is part of the fairway. To go back and label the piece that defines the "outer" boundary of the multipolygon incorrectly as it says that *everything* within that border is a fairway. Hope this helps. Please let me know if you have any questions.
