Sounds like extensive efforts writing blueprints for a cathedral.
While it'd already be siesta time in the bazaar having earlier eaten your lunch.
The article argues for pretty much the opposite of that approach. It says not to wait until you've debated architecture, made mockups, or done other things that take a bunch of time. Instead, start by shipping to your production servers on day one.
That's why I wrote blueprints to a cathedral, not a cathedral. Your post still reads as highly opinionated on assertion of how to work.
