 We want to maintain a welcoming atmosphere for contributors, so use a friendly
 message when closing the PR. Example message:
 
-    Thanks for contributing! I'm closing this PR for now, because it still
-    <fails some tests OR has unresolved review feedback OR has a merge conflict>
-    after three months of inactivity. If you are still interested, please feel free to open
-    a new PR (or ping us to reopen this one).

+### Closing PRs for future standard library changes
+
+*See also the [guidelines in the CONTRIBUTING file](./CONTRIBUTING.md#standard-library-stubs).*
+
+When rejecting a PR for a change for a future Python version, use a message
+like:
+
+    Thanks for contributing! Unfortunately, [as outlined in our CONTRIBUTING document](https://github.com/python/typeshed/blob/main/CONTRIBUTING.md#standard-library-stubs) we only accept pull requests to the standard library for future Python versions after the first beta version has been released. This is in part to prevent churn in the stubs, and in part because the testing infrastructure for the future version is not yet in place. Please feel free to open a new PR when the first beta version has been released. Alternatively, if this PR is still relevant, you can leave a comment here to reopen it.
