We've had sixty years of serious software development and the community still doesn't have a strong idea of how to actually write applications in the manner you describe and then evolve those applications according to new requirements. Every decade we get tons and tons of new best practices and the fact is that virtually all applications, even those written by world experts, end up as a mess.

"Just write code beautifully" is a great problem to try to solve, but we shouldn't let that problem prevent us from making minor local optimizations in engineering practice.
