That's pretty cool. Layers are so much better for Python dependencies than the other solutions. They make code changes much faster to deploy. I also used layers in a recent project of mine. But instead of using Docker, I opted to build the layer in a special builder Lambda function. It's then used as a custom resource which outputs the S3 path and finally a layer resource uses that to create the actual layer.
