There's even talk in the PowerShell world about Invoke-Command directly accepting HTTPS URLs to scripts, but in addition to some security questions, it is caught in a catch-22 that not enough of these scripts are Signed so there's not enough demand for it, but if more tools like this were doing code signing there's a world where the code golfed instructions are just `icm https://yourdomain.com/some/script.ps1`, and it is more secure than these examples with (`&` or `iex`) and `iwr`.
