This smells more like the fluidity of what people mean by “junior” more than anything else. Journeymen engineers in their over-engineering phase, or even very “senior” expert programmers can suffer over fitting the product to their own mental model. The most senior judgment is to understand when an abstraction makes sense at a customer level, because that defines the durability of a business-logic abstraction.

I do agree this happens with the senior overengineering phase, but the comment I replied to mentioned "especially juniors" and I've heard this trope specifically about juniors, with the implication they want to apply what they learned in college, but this hasn't been my experience at all.
