I'm not disagreeing in general, but I need to point out that this is like saying you should write Arabic numerals in order of decreasing powers of 10 because it autosorts on a computer.
It's the reverse. Computers automatically sort Arabic numerals and dates written in decreasing powers because those are the correct formats.
