If two crates have the same name, distinguish them in rustc's output?

Code

I'm writing code that uses the py-spy and remoteprocess crates. py-spy also uses remoteprocess internally. I tried to switch to using a different version of remoteprocess with some patches, but I foolishly did this by changing my top-level crate to depend on remoteprocess = { git = ... }, when what I really wanted was to use a [patch.crates-io] stanza. Anyway, the end result is that I had two different remoteprocess crates in my dependency tree without knowing it, and rustc gave me some spectacularly confusing errors. In particular, in a single message output, it suggested to try adding the line use remoteprocess::SomeTrait, and also suggested removing the line use remoteprocess::SomeTrait because it was unused.

Current output

help: the following trait is implemented but not in scope; perhaps add a `use` for it:

  |

  |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Desired output

It'd be nice if rustc detected this case and printed something hinting at what's going on?
