BUR #16004 has been rejected.
create implication simple_background -> featureless_background
this is a proposal for backgrounds which one can not identify the background with anything(a "test" for this would roughly be "does it look like the picture is taking place in an identifiable location?" post #6155521 is the current example of what this tag would be like, and i imagine there would be hashing out what exactly qualifies a background for this tag
the BUR is under the assumption that if it is a simple background, it is also a featureless background
