Semantically, a one-dimensional list/array of “things” can be trivially transposed into a series of lines with a linebreak separator, but I don’t think the same holds true for a “list of lists” (2-dimensional data) or a “list of lists of lists” (3D data) etc. At least without a standard begin-end list delimiter that allows nesting.

Just thinking about a way that perhaps an old tool can be “wrapped” to be tricked into working with 2+-dimensional data by somehow divvying up the 2+ dimension input data into concurrent 1-dimensional streams, but this seems to require a way to represent more than 1 dimension of data without breaking existing utilities (unless there was, like, a wrapper/unwrapper layer that handled this...)
