The 9 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. The 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in this thread: https://edk2.groups.io/g/devel/message/53712 (the code branches shared in that discussion are now out of date, but the whitepapers and discussion are relevant). On a separate note, shallow threading might not work on this patch series due to changes made by the SMTP server. Please bear with me while I am investigating if this can be changed.
