I agree to a small extent, but this is very field dependent. Social sciences, where you're taking a bunch of data and running a Python, R, or Julia script against it? Sure. Require the PI to archive the data (or anonymized version where PII is an issue) along with the script and a quick description of the method. When you cross over to more STEM oriented fields, tacit knowledge (e.g., the 'experience' or stuff you pick up from your colleagues) becomes much more important. Reproducibility is still important, but you can only expect the PI to provide so much knowledge before it becomes untenable.
