Is Chalice still Supported?

AWS Chalice (https://github.com/aws/chalice) still appears to be supported according to docs and the README, however https://github.com/aws/chalice/issues/2053 has been open since July asking for Python 3.11 support, and AWS announced 3.11 support for lambda back in August (https://aws.amazon.com/about-aws/whats-new/2023/07/aws-lambda-python-3-11/).

There's an existing Pull request https://github.com/aws/chalice/pull/2063 that has many people awaiting support with no action. So I'm curious if AWS no longer supports Chalice? Or if it was just forgotten about?
