Not that I have come across. I have started to use Powershell quite
extensively in my Wpkg files with only minor issues, mainly to do with exit
codes and quoting\escaping.

Here is an example that turns on Powershell remoting:

<?xml version="1.0" encoding="UTF-8"?>

<packages
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="../xsd/packages.xsd" >

    <package id="ps-remoting"
            name="Enable Powershell Remoting"
            revision="1"
            reboot="false"
            priority="10">

        <check type="execute" path='powershell -NonInteractive -Command "if
(Invoke-Command localhost {1}) {exit 0} else {exit 1}"'
condition="exitcodeequalto" value="0"/>

        <install cmd='powershell -NonInteractive -Command
"Enable-PSRemoting -Force"'/>
     </package>
</packages>

You can run script files as follows, but I have found that exit codes
always report success despite the script commands failing.

<install cmd='powershell -NonInteractive -File "<path to .ps1>"'/>

You might find running powershell /? at the command prompt useful.
