I work in academia in a STEM field. I've never seen or heard of a reviewer asking for access to the raw data used to produce a paper. Reviewers typically operate under the assumption that you're not trying to deliberately mislead them about how you collected and evaluated your data (and I think they have to, at least with how the system currently works).

What often happens is that, although the time they get to spend on a single paper is limited, reviewers still come up with important criticisms that end up leading to substantial changes (sometimes multiple rounds of them) or even an outright rejection.
