    Yes, wit-bindgen is the way forward here. It's under active development, though a lot of the basic interface-types functionality is implemented and usable. As an example of it in action, check out the wit interface files in this project: https://github.com/deislabs/spiderlightning/blob/main/docs/primer.md
