Not everything is at scale. We have adopted these techniques (at the beginning of this year) for our internal web frontend to our build system at work and it makes it possible for all of the team to work on this system without having to setup a complex node environment or deal with npm. We also get the pretty shiny that Tailwind brings to the table. Our system is as simple as can be but not any simpler.
I had to get some login issues fixed working for a big tech company that had outsourced that particular set of work. The Indian person I interacted with could not give a fuck less. Total burnout, I felt bad for him.
