Plan to implement:

Get-ChildItem; Add IncludeRoot Switch

Suggestion: Currently if you wish to fetch an item and its children you have to make a call to Get-Item and Get-ChildItem. Since this is a common use case, it would be good to reduce this to a single call. By adding an IncludeRoot switch to Get-ChildItem we could easily have it fulfill this requirement.

Here are some examples of people who've hit this scenario & tried to get creative in resolving it.

Motivation

As a PowerShell user,
I can retrieve an item and its children,
so that I have the full tree returned in a single result set.

User Experience

Example of user experience with example code/script.
Include example of input and output.

Get-ChildItem -Path 'c:\demo' -IncludeRoot -Recurse | Select-Object -ExpandProperty FullName

c:\demo
c:\demo\subfolder
c:\demo\subfolder\one.txt
c:\demo\subfolder\two.txt

Specification

Include [Parameter()][Switch]$IncludeRoot in the list of available parameters.

Alternate Proposals and Considerations

The current workaround is to make separate calls to Get-Item and Get-ChildItem.

Start with the RFC text and the linked examples to understand the requested Get-ChildItem workflow. Review the current -Recurse behavior and the proposed IncludeRoot parameter and output. Done means the RFC's parameter, usage example, output, and design considerations are resolved well enough for implementation.
