I did consider making this the central theme of the post but it probably warrants a second one. The difference is that we are scared of different things. You are scared of bloat, and duplicating code which makes it much more work to make changes to the design system.

I am scared of complexity. Having a code base where you need to hold too much information in your head just to make a simple style change. I am so scared of this, that I am more than happy to accept a code base that is much less DRY.
