This functionality was originally needed to handle binary only crates (crates which do not have a library in the same package either implicitly or explicitly). "Extra workspace members" were crates downloaded and added as a workspace member so
crate_universe
could generate a dependency graph with that crate included.However, given the recent implementation of #1381 and the existing example of //examples/crate_universe/cargo_remote, there's support and examples for this outside of needing to have the "extra workspace member" functionality built into
crate_universe
.Instead of relying on this bespoke functionality, Cargo has recently added support for binary dependencies (rust-lang/cargo#9096). This functionality should provide a much better solution going forward.
