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://github.com/tianocore/tianocore.github.io/wiki/VariablePolicy-Protocol---Enhanced-Method-for-Managing-Variables#platform-porting 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in this thread: https://edk2.groups.io/g/devel/message/53712 (the code branches shared in that discussion are now out of date, but the whitepapers and discussion are relevant).
