I'm currently writing [`cargo-guppy`](https://github.com/facebookincubator/cargo-guppy), a toolkit for analyzing Rust dependency graphs. As part of that I'm writing some tests to compare guppy to `cargo`, to ensure that it produces the same results for the subset of analyses `cargo` can do. While writing tests I found it useful to distinguish between packages that weren't present at all and packages that were activated but with no features. This commit adds that functionality to the `_unverified` method.

Yeah, I'm using it as a library in tests. |

Hi there! :)
I'm currently writing
cargo-guppy, a toolkit for analyzing Rust dependency graphs. As part of that I'm writing some tests to compare guppy tocargo(see facebookarchive/cargo-guppy#126), to ensure that it produces the same results for the subset of analysescargocan do.While writing tests I found it useful to distinguish between packages that weren't present at all and packages that were activated but with no features. This commit adds that functionality to the
_unverifiedmethod.(BTW, of possible interest to @ehuss, I've also found some interesting behavior differences between the v1 and v2 resolvers. Will file issues for them soon!)
