Failiure when building a wheel from a rust crate with a local dependency

[IBims1NicerTobi]

I have a rust crate in a workspace with a local dependency. Basically I have

project_workspace_dir
├─project-core
└─project-python

And my project_python depends on project_core in Cargo.toml like this:

[dependencies]
project-core = { path = "../project-core" }

When I call python -m build -s I see the following in my logs:

creating project-0.1.0/../project-core
creating project-0.1.0/../project-core/src

and

copying ../project-core/Cargo.toml -> tr0-0.1.0/../project-core
copying ../project-core/src/error.rs -> tr0-0.1.0/../project-core/src
copying ../project-core/src/lib.rs -> tr0-0.1.0/../project-core/src

This leads to project-core ending up next to dist

I think the optimal solution here would be to detect local dependencies, actually copy them to the archive and rewrite Cargo.toml for the affected crate, but I'm not sure how reasonable that is.
