Perceived non-deterministic error:

*RFC*
https://github.com/PowerShell/PowerShell-RFC/blob/master/RFCNNNN-New-RFC-Template.md
Title: Copy-Item should not fail with error "Container cannot be copied onto existing leaf item"
Motivation:
As a [<<user_profile>>] -> (https://github.com/penalvch),
I can <<functionality>> -> What?!,
so that <<benefit>> -> Powershell doesn't setup people to fail on normal expectations of how copying a file or using a basic cmdlet like copy-item works (e.g. interoperability and expectations when context switching from different languages and computing norms).
User Experience: See above and below.
Specification: See above and below.
Alternate Proposals and Considerations: None.
