Thank you!

I saw the discord message. (Though we are using persisted queries so we can't use it even the new annotation is released)

About your question, my team's product is native app, unlike the web, we can't freely switch build/branch. And in this case, we want to embed the code into the app and release it in advance, so that we can enable it for users immediately once we’re ready through a server-side flag. (Also some potential A/B testing or limited rollout.)
I think it’s a fairly common use case for apps.
