Implement a Change Reviewer Group feature
Lots of organisations are using code technologies like ARM Templates/PowerShell/Az CLI/Terraform to manage their Azure Tenants which can allow a team to perform a review on changes made to an environment.
However there are organisations that currently use the Portal and only the Portal for implementing any changes to resources.
I propose that an Azure Tenant / Subscription / Resource Group / Resource should allow for a enforced Change reviewer group feature where any changes made can need to be signed off and reviewed by another set of eyes in the team.
This likely feels like a enhancement to the already existing Locking feature.

An essential feature moving forward for governance
