@kristoffer.carlsson would be best qualified to answer, but I will try based on my interpretation of

- [Add support for "package extensions" to code loading by KristofferC · Pull Request #47695 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/pull/47695/files) .
- [Code Loading · The Julia Language](https://docs.julialang.org/en/v1.9.0-rc1/manual/code-loading/#man-extensions) (dev version)
- [5. Creating Packages · Pkg.jl](https://pkgdocs.julialang.org/dev/creating-packages/#Conditional-loading-of-code-in-packages-(Extensions)) (dev version)

From what I can tell, the extension mechanism is primarily focused on extending methods, not necessarily introducing or exporting new types.

Based on [Are extension packages importable?](https://discourse.julialang.org/t/are-extension-packages-importable/92527/1) it might be possible to get a reference to the extension module itself.
