Thanks for the PR! It's great, although I think it's a bit more complex.
I would like to see a test covering this example: https://doc.rust-lang.org/cargo/reference/workspaces.html#the-members-and-exclude-fields

[workspace]
members = ["member1", "path/to/member2", "crates/*"]
exclude = ["crates/foo", "path/to/other"]
