Revert "Use flat_map { } instead of map {}.flatten"
This reverts commit abf8de85519141496a6773310964ec03f6106f3f. We should take a deeper look to those cases flat_map doesn't do deep flattening. irb(main):002:0> [[[1,3], [1,2]]].map{|i| i}.flatten => [1, 3, 1, 2] irb(main):003:0> [[[1,3], [1,2]]].flat_map{|i| i} => [[1, 3], [1, 2]]
