It would be up to "the community" to make modules to do this kind of thing, which would be possible if anyone wanted to, but unlikely to ship with Windows.

Microsoft's push is to avoid more "bloat" by leaning more heavily on optional modules installed from the PS Gallery. But `group-object` is a builtin for doing a kind of SQL GROUP BY operation, and Measure-Object just gained a -StandardDeviation option, and there's now ConvertTo/From-Json, and ConvertFrom-Markdown. If there is a basic routine that would be popular and fit many use-cases, you could request it at https://github.com/powerShell/PowerShell/issues/
There is a GPL licensed scientific computing framework called Accord.NET, it's not wrapped for PS but can be used almost directly, and some of these others might be viable as well:
