The `test_utils` package has a non trivial public API (e.g. it exposes rand) even though the code is fairly simple It would be nice to make this crate more self contained and thus I think we should deprecate and eventually remove `test_utils` from the public API > > It may just be better to avoid using the arrow bench_utils at all. > > +1 > > But it's also a good idea to merge this. What do we think about merging this and marking all of bench_utils as deprecated (pointing out that external users should just copy the code into their repo if they want to use them) 🤔 _Originally posted by @alamb in https://github.com/apache/arrow-rs/issues/7128#issuecomment-2668343791_
