All true.
But there's a little bit of a difference between mm/MM being minutes/months, where at least as someone thinking about datetime formatting you likely have a concept that the concepts of minutes and months are plausible things 'm' might stand for, vs. yyyy/YYYY where unless you've come across it before, the idea that there might be an inbuilt concept of a 'week year' is likely not going to be something that occurs to you.
I suppose the fact that both 'yyyy/mm/dd' and 'YYYY/MM/DD' produce values that are obviously wrong most of the time should be enough of an incentive for developers to go and look. up the codes. But that said, 'YYYY/MM/DD' produces what looks like the right answer for most of January...
