@zrquan thanks for the PR. This is a breaking change. I suggest you create a separate extension for different code execution tools, and you can manage the package and publication of the package to PyPI. We can add link to the extension.

Got it. Also, when I want to contribute a new extension, should I create my own repo instead of committing a PR directly to this repo?
