I dont know, the paper that described waterfall used it as an example of what not to do, they covered the better method on the following page but it seems people only read the "headline".

Which of course is not an argument in itself against parent's point.

Very true but thought it was worth mentioning, the original paper is very readable and it's amusing that waterfall lasted until the 90's when it originated in 1956 and the paper covered the flaws in 1970.
