Bump.
Now that the stable tag is behind us, I’d like to get this in to have maximum time before the next stable tag.
I think the only reviews I’ve seen so far are for the platform integrations (Arm, Ovmf, and Embedded). Need more eyeballs, please and thank you!

Subject: [EXTERNAL] [edk2-devel] [PATCH v5 00/14] Add the VariablePolicy feature
REF:https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.tianocore.org%2Fshow_bug.cgi%3Fid%3D2522&data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&sdata=k9X9qPTDTQlno5%2Ff4koMn6bE9s6nTOIlJ886PQRw%2Bzc%3D&reserved=0
The 14 patches in this series add the VariablePolicy feature to the core,
deprecate Edk2VarLock (while adding a compatibility layer to reduce code
churn), and integrate the VariablePolicy libraries and protocols into
Variable Services.
Since the integration requires multiple changes, including adding libraries,
a protocol, an SMI communication handler, and VariableServices integration,
the patches are broken up by individual library additions and then a final
integration. Security-sensitive changes like bypassing Authenticated
Variable enforcement are also broken out into individual patches so that
attention can be called directly to them.
Platform porting instructions are described in this wiki entry:
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Ftianocore%2Ftianocore.github.io%2Fwiki%2FVariablePolicy-Protocol---Enhanced-Method-for-Managing-Variables%23platform-porting&data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&sdata=eIQjfZJQGTECXzETa1iZ3T9vOdNiNEjIzVrjhDR%2B2CE%3D&reserved=0
Discussion of the feature can be found in multiple places throughout
the last year on the RFC channel, staging branches, and in devel.
Most recently, this subject was discussed in this thread:
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fedk2.groups.io%2Fg%2Fdevel%2Fmessage%2F53712&data=02%7C01%7Cbret.barkelew%40microsoft.com%7C90bcb822fa054686203008d807a3e4ee%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637267747784879051&sdata=rhwUXzkU%2B71sFkomJvPzi4IN6hz2JKIbDBnNt0wCJS8%3D&reserved=0
(the code branches shared in that discussion are now out of date, but the
whitepapers and discussion are relevant).
