I really agree with this. There was a company that I worked at 10ish years ago with a SaaS built around Drupal. They had one monolithic css file that was 25000 lines. It was a nightmare. When I took over the front-end rebuild, went through it line by tedious line and broke it out into discrete components. I think about that from time to time when building logic or other functionality. I'd much rather have a self-contained bit of code than a big thing that is so intertwined I'm terrified to touch anything.
