Confused about state of cloudfront EdgeFunction - experimental but not in an alpha module?

[dan-lind]

I read about how alpha modules work in this blogpost
We can read here that After an alpha module stabilizes, it will be moved to aws-cdk-lib and have a guaranteed backwards compatibility within the AWS CDK major version.

I'm building a cloudfront distro which will use some edge lamdbas, and I'm confused about the fact that the EdgeFunction actually sits in the stable aws_cloudfront module, but in a package named experimental.

So based on the blog post, the function should be stable since it exists in aws-cdk-lib, but the experimental name suggests otherwise.

Can someone help me understand the current state of EdgeFunction?
