Defining what to build in enough details is how you get the business logic nailed down (aka essential complexity, aka the domain in DDD). Code is just formal writing and architecture is there for maintenance (a program can be in a single file).

Sure there are accidental complexity like the intricacies of the tech, but those are actually explained very well in the docs.
