Im no expert by any means (and we haev a few around here) but my kiddos both go to M school. I would think the reason they do not like to introduce it to late is because by five they have had many lessons to get them to the point they are at. With Montessori school a lot of the lessons lead to another lesson and they start off small.
I do know our M school has taken on 5 year olds that are the right fit so it is not completly out of the question either.
