New security feature in September 2021 Cumulative Update for Exchange Server

Exchange Team... please consider reverting applied mitigations automatically when they have been fixed in an SU or a CU...  As an Exchange Administrator, I cannot constantly babysit what mitigations are in place via EM, remove the ones that are deprecated by a SU or a CU: which involves looking up how to undo the mitigation, a process which is not made clear in this article... Will there be a catalog of mitigations?  Will it explain how to revert a mitigation once superseded?!?

"The steps to remove a mitigation that’s no longer needed depend on the mitigation itself. For example, if as part of a mitigation an Exchange service is stopped and set to disabled, then removing the mitigation involves starting the service and setting it to automatic startup. To remove an IIS rewrite rule mitigation, an admin can delete the rule from the appropriate web site using IIS Manager. As illustrated in the following figure, the EM service creates IIS rewrite rules with a prefix of “EEMS <Mitigation ID> <Description>” making them easy to identify."

However well intentioned, I cannot allow an automated service to make changes to my Exchange configuration without an automated way to rollback those configuration changes...

For these reasons, unfortunately, I'm leaning towards: Set-OrganizationConfig -MitigationsEnabled $false

Thank you.
