Yeah, but waterfall requires that management knows what they want. It’s impossible!

A software engineer was not involved in this if waterfall is painted positively.

I think the last time I heard an engineer unironically advocating for a waterfall IRL was about a decade ago and they were the one of the crab-in-a-bucket, I-refuse-to-learn-anything-new types—with that being the very obvious motivation for their push-back.
