@Mikko Kotamies Thanks for your patience on this. I have checked with internal team and sharing the below.
Our app service engineering team has confirmed GO
runtime is going to be deprecated as option to create the app service.
Alternatively, if you want to run your GO
runtime application on app service. It is suggested to deploy using custom container.
I have relayed this feedback to content author team and the respective changes to documents will be updated soon.
Feel free to reach back to me if you have any further questions on this.
