Crater run for `unit_bindings`

[jieyouxu]

Wanted to see how many crates might be affected if we start to warn on unit_bindings.

Praying to craterbot that I can find the right incantation 🙏

Closing as even a cursory glance suggests to me that if we do warn on this by default, it probably needs to be over an edition boundary.
