Code Review

The pull request removes an older region tag from the app.yaml file. The change seems straightforward and aims to clean up the configuration file. However, it's important to ensure that the removal of this tag doesn't impact any existing functionality or documentation that might be relying on it.

Summary of Findings

• Region Tag Removal: The pull request removes the [START app_yaml] and [END app_yaml] region tags. It's important to verify that no other part of the codebase or documentation relies on these specific tags. If they are still in use, removing them could break functionality or cause confusion.

Merge Readiness

The pull request appears to be a simple cleanup task. However, before merging, it's crucial to confirm that the removed region tags are indeed obsolete and not used elsewhere in the project or documentation. I am unable to directly approve the pull request, and users should have others review and approve this code before merging. I recommend verifying the usage of the removed tags before merging.

you're going to need to modify the page that is using app_yaml before you can remove this

1. You are going to have a conflict with the rename in PR chore(gae): Remove older region tag #4032 for file appengine/building-an-app/update/app.yaml.

2. The fixed region tag requires a language suffix for node

See polls.yaml#L25 as an example, and the internal resource naming-a-new-region-tag

~ ~ ~

You could use gae_build_app_yaml_node.
