No, I think the other side has a point. If I were doing 10 services on my car, I would have muscle memory of a lot of things. If I am doing only brakes, and maybe another thing, I do not have that muscle memory. While the work may not be harder, the familiarity is gone for a lot of people.

BTW just before Covid, or during Covid, I took a car mechanic course from the local De Anza college - no hands on, so that's why I think it was during Covid. But after 5 years and no experience, I have forgotten except the abstract concepts. Then imagine people who never had to look under the hood -- ever.
