xcode 13 production and the managment of certificates in the cloud

I'm waiting for the production version of xcode 13 so I may build an app where the certification process is managed the cloud. I intend to build a new app rather than update my existing ones so I learn more about the touted change of Apple managing certificates in the cloud rather than high maintenance way its done today.

My problem is exacerbated by the fact that I use Apple Pay and third party payment gateways. With that said, when is xcode 13 production going to be released? Does it really help lower the maintenance of apps? Should I create another forum?
