I guess it's dangerous to use words like "nobody" or "everyone" or "always" or "never" on the overly pedantic Hacker News. I would hope that the sentiment of my point came across either way. If not, let me clarify: it's generally preferred to spend engineering effort on building new features and optimizing code to improve performance etc. over e.g. rewriting code from scratch to simplify it's maintenance. I would venture to guess that an overwhelming amount of engineering effort is spent on effectively adding complexity to code.
