The tag alias #59529 nature -> nature_background has been rejected.
Reason: Functionally synonymous. If nature is present, it will be a background, and if there's a nature background, there's nature. The wiki for nature says
Outdoor scenes with notable emphasis on wild plants and greenery, or other lush scenery. Not applicable to barren or artificial landscapes.
Only for fully natural scenery. No elements such as fences or roads should be visible.
However, no one is using it that way. There's only a few results in the first couple of pages of results I looked at that could be said to have a notable emphasis on wild plants and greenery, while there's plenty of examples that are barren or include unnatural elements in just the first page. Additionally, nature_background, which has no wiki and no description for proper use, implicates nature, which undoubtedly is a big factor in this rampant misuse.
A tag for "notable emphasis on wild plants and greenery" with only "fully natural scenery. No elements such as fences or roads should be visible." would need a better name than nature as it's obviously too ambiguous, and too much of what's currently under nature wouldn't apply, so it can't be renamed or mass updated to it.
EDIT: The tag alias nature -> nature_background (forum #351420) has been rejected by @gattonero2001.
