Less code isn't as important as it used to be, because the cost of maintaining (simple) code has gone down as well.

With coding agent projects I find that investing in DRY doesn't really help very much. Needing to apply the same fix in two places is a waste of time as a human. An agent will spot both places with grep and update them almost as fast as if there was just one.

It's another case where my existing programming instincts appear to not hold as well as I would expect them to.
