Review comment:
       after the second if we have some logic that should be done without 
checking SDK:
   ```
   ...
   if !ok {
     if sdkEnv.ApacheBeamSdk == pb.Sdk_SDK_GO {
       // code for the Go SDK only
     }
     // code for all SDK (including Go SDK after the top part)
     return
   }
   ...
   ```
   
   If I join these 2 `if`s it will be something like:
   ```
   if !ok && sdkEnv.ApacheBeamSdk == pb.Sdk_SDK_GO {
     // code for the Go SDK only
     // code for all SDK (including Go SDK after the top part)
     return
   }
   if !ok {
     // code for all SDK (including Go SDK after the top part)
     return
   }
   ```
   
   So I think it's better to use present code.
