SSGI is in the 4.23 release, however, it can only be enabled via console variable at this time. It’s not a final, production-ready feature and we are not calling it out in the release notes or marketing it in any way for this release. There is still some work to do with it and it should be ready for 4.24 with more information and accompanying documentation. Until then, it’s there in the builds if you want to try it out but it’s hidden.
