Assigning single purpose to things is not necessary. "Systems are what they do" is a quote for a reason.

I think in addition to rules survival and admin self-concern, people genuinely underestimate how much maintenance and effort go into accomplishing goals in an organized, communicable, trustable way. It is also why AI is not as successful as people thought it was going to be at taking over jobs.

If you think the only value add to a business is the business output, you are taking admin work for granted.
