I'm wondering if it's possible to use LLMs to generate a nice weekly summary like @alamb does in [this issue](https://github.com/apache/datafusion/issues/15269). It doesn't need to be as good as what alamb currently produces—getting 80% of the way there would still be a great result for us.
