`PSReviewUnusedParameter` false positive for ValueFromPipeline and current process item `$_`

iRon7

The ValueFromPipeline doesn't require the literal name but just the current item ($_) in the Process block:

[CmdletBinding()]
param (
    [Parameter(Mandatory=$true, ValueFromPipeline=$true)]$InputObject
)
process {
    $_
}
