Most of the time, yes. I maintained my vimrc for maybe 10-15 years before I gave up on it.

The hard part of maintaining a config is that there's no such thing as cost-free usage, it always takes a mental toll to change a config, to learn a new config, to remember which configs are in use and what they do, to backup configs, or at least to setup and maintain a config-auto-backup flow.

By far, the easiest mental model is just learning how everything works out of the box, and getting used to it. Then again, sometimes what people want is to do things the hard way for its own sake. That's probably part of why I kept going back to C over and over for so many years.
