Why would we expect a statistician/data analyst to write an OS? I'd expect them to write reports, white papers, articles, and functional domain-specific packages for R or Python. Especially in my field of healthcare, where over 50% of the analysts use SAS, I doubt we'll see any groundbreaking innovation, at best it's incremental changes via papers or sharing code.
