I would argue that this is even worse than replacing the wrong part.

Agreed. I was speaking to people who just throw parts at a car (for example, the car's idle wanders, so with no diagnosis let's just replace the IAC valve.) I've seen that exact scenario a few times and not once has it actually fixed the issue.
Fixing a big issue and then finding that there are smaller problems remaining is a whole different game, as long as the first fix was actually needed. Another example: We had a lady come into the Ford shop I worked at for oil changes. She did her oil changes there, and for about 2 years every time we topped off her rear differential and told her that her axle seals were leaking, and should be replaced. Well she she finally agreed to having the work done, and when we got underneath her pickup we found that she not only needed axle seals, but she needed new axle shafts (groove worn in from 2 years of running dry), and an unrelated fix was that she needed new fuel tank straps. We wouldn't have found the the rusted out fuel tank straps if we hadn't been up under the axle working on all that.
