UseProcessBlockForPipelineCommand returns a warning when pipeline behavior is explicitly disabled

I've noticed that UseProcessBlockForPipelineCommand rule produces warning notifications when pipeline behavior (ValueFromPipeline, ValueFromPipelineByPropertyName) is explicitly disabled.

Steps to reproduce

Function Get-Number
{
    [CmdletBinding()]
    [OutputType([int])]
    Param(
        [Parameter(ValueFromPipeline=$false)]
        [int]
        $Number
    )

    $Number
}

Expected behavior

The rule should not report any findings

Actual behavior

首先复现 PowerShell 示例并跟踪 UseProcessBlockForPipelineCommand 规则的入口点，重点关注显式设置为 false 的 ValueFromPipeline 和 ValueFromPipelineByPropertyName 值。定位该规则现有的测试，为此情况添加覆盖，并确认该示例不会产生任何发现。
