yeah good question, if you're doing any sort of analytical work, then you'll care about the statistical distribution of your data. If you're running queries or sharing data with third parties, then you want to maintain the same stats. If you're just building features then you might not care as much as if you were doign analytical work. But it could still be relevant if you're building metrics/dashboards/anything visual - you'll want to see that you can render your prod data correctly. So more so for analytical work but less so for normal, run of the mill dev work.
