Maybe this is a silly question, but what advantage do you get from checking that huge file into VC instead of just installing parallel ahead of time on the CI images?

Not a silly question!

In this case, we don't have control over the docker images used to build our apps.

Parallel was born way before docker and modern CI practices. Having one script that did it all was more of a benefit before those become commonplace
