Nice work.
I was looking to update it too.

Please have a look at my comments

After our meeting with @olivhoenen I understood I could add small work to your fork/branch directly

I've added some commits I had laying around... the last one is probably not what you want -- but how can we run alternative python versions with a single uv.lock file?

uv is designed to support multiple Python environments in a single lock file by default, so we shouldn't run into any issues running alternative versions.
