**Summary of the new feature** Currently $SuppressAzurePowerShellBreakingChangeWarnings variable warns with UseDeclaredVarsMoreThanAssignments however $WhatIfPreference does not. Should this be added to default list of ignore rules or too specific to Az Powershell cmdlets? <https://github.com/Azure/azure-powershell/blob/master/documentation/breaking-changes/breaking-changes-messages-help.md> <https://github.com/Azure/azure-powershell/blob/preview/documentation/breaking-changes/breaking-changes-definition.md> **Proposed technical implementation details (optional)** Add this to list of default exceptions for UseDeclaredVarsMoreThanAssignments rule in Engine/SpecialVars.cs. **What is the latest version of PSScriptAnalyzer at the point of writing** v1.19.1
