Hard-coding a seed would remove the run-to-run randomness, too, so would remove the need the `randomness` tag if this utility were to be used from a functional test. But yes, the reason to not do true randomness when setting up data for micros is to ensure we don't get multimodal results from arbitrary differences in the data setup. There are other ways around that, e.g. randomize data continually between iterations, run more forks to get more samples about flicker etc. A lot of work with an end result which is unlikely to add little more quality than a "random" set of data that we keep static from run-to-run.
