Sorry Python but it is what it is.

Idk, maybe you can share the common packages across projects. (That can never go wrong, right? /s)

Sources are shared, sharing compile-time artefacts is done within workspaces.

You can globally share compile artifacts by setting a global target directory in the global Cargo config.
In $HOME/.cargo/config.toml:
[build]
target-dir = "/path/to/dir"
The only problems I had when I did it where some cargo plugins and some dependencies with build.rs files that expected the target folder in it’s usual location.
