Description
It's always been recommended to avoid using Write-Host because it outputs only to the console and not to any of the standard output streams. As of PowerShell 5.0, Write-Host is just a wrapper for Write-Information and thus outputs to the standard output streams similar to the other Write-* cmdlets.
Should the use of Write-Host still be flagged as something to be avoided? Is it possible to implement a rule that only flags the use of Write-Host if the computer is running a version of PowerShell earlier than 5.0?
Thanks!

Research direction
Start by reviewing the existing analyzer rule that flags Write-Host and the linked PowerShell documentation for Write-Host behavior in version 5.0 and later. Determine how the analyzer handles PowerShell version differences; done means the issue's requested version-aware behavior is implemented and covered by appropriate rule tests.
