Summary of the new feature / enhancement

I am working on adding new Tar APIs in .NET 7.0: https://docs.microsoft.com/en-us/dotnet/api/system.formats.tar?view=net-7.0

It would be great if we could offer Cmdlets in PowerShell for these APIs, both for archiving (*.tar) and for archiving + compressing (*.tar.gz).

How can I help to make this happen?

Proposed technical implementation details (optional)

Here is a detailed explanation of how the APIs can be used as of .NET 7.0 Preview 4: dotnet/core#7378 (comment)

Note: There will be some minor API changes in the next Previews, but most of the functionality is like in the linked comment.

Known bugs

I created this uber issue to track pending feedback to address: dotnet/runtime#68230
