I disagree with the conclusion. I agree on the best practices you mentioned, and I follow them when working in Julia (and the Julia Manifest.toml files provides for much better reproducibility compared to e.g. conda). Avoiding recompilation of code that has not changed is not at odds with rerunning your computational pipeline often to ensure reproducibility. It is true though that you can not translate the muscle memory you have in R to Julia. Also, I would say actual best practices would be to have CI, not to be rerunning your code manually.
