pry
[1] pry(main)> x = {a: {b: 1, c:2}}
=> {:a=>{:b=>1, :c=>2}}
[2] pry(main)> x.flatten(1)
=> [:a, {:b=>1, :c=>2}]
[3] pry(main)> x.flatten(2)
=> [:a, {:b=>1, :c=>2}]

The documentation of Array#flatten is pretty clear:

"...That is, for every element that is an array, extract its elements into the new array."

So it follows the documentation and would create massive incompatibilities to change!
