Good point the analogy definitely doesn't completely account for the adjacent field of software engineering, where coding styles are certainly important. I guess that's mostly because artists rarely work in large groups, and when they do, I'd imagine the work is mostly parallelize-able: several people don't need to go through the details of any single piece of work.

Animation. Easy to work in parallel but output is very constrained stylistically. Multiple author books tend to have stylistic constraints as well otherwise the book suffers from an uneven feeling.
