Just to let you know:
https://hammerstone.dev/sidecar/docs/main is missing Python 3.9.
And the README is missing Node 18 and Python 3.10 and 3.11, which are now listed in AWS: https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html
I agree there is a link to the AWS list on the page, but the list says "any of the following runtimes".
I suggest just listing Node, Python, Ruby etc generically and referring to the AWS page, if it is indeed the case that all AWS-supported runtimes will work.
Thanks for a great package!
