Of course 90% will use zip packages, container support is relatively new in the lifetime of Lambda.

Deprecating zip packages doesn’t mean zip packages no longer work, it means pretty much what they’ve done, ignored the managed runtimes with the view if the current runtime doesn’t do what you want, make your own with exactly what you need using tools you are likely already using with no vendor lock-in.

For things like Python most people don’t care about the underlying operating system from the projects in multiple orgs I’ve worked in. They go to Dockerhub, type Python, pick the image with the highest downloads and run pip install inside it. If you use Go, Rust, anything that creates a static executable you use “FROM scratch” with the only thing inside the container being the executable.

Those who do care about the underlying image are likely large orgs with a set of already blessed base images or people using things like Nix to build containers.

From a large org perspective and developer experience getting a “registry” for free because packaging as a standards compliant OCI image means instead of effectively creating your own registry on top of s3, you get a far more robust one with tagging, asset hashes, layering etc out the box. I never had a issue with zip archives but containers removes a bunch of roll your own boilerplate registry.
