Description

IMO, Traits should be auto-imported as _ if https://rust-lang.github.io/rust-clippy/master/index.html#unused_trait_names is enabled and I'm not actively trying to import the trait name. I'm not entirely sure whether changing behavior depending on clippy configuration is in scope, though, or whether this behavior is better implemented on the editor side of things.

Research direction

Start by tracing rust-analyzer's auto-import handling for traits and determine how Clippy configuration is exposed to that path. Compare the current behavior with the unused_trait_names lint and resolve whether the change belongs in rust-analyzer or the editor. Done means the intended behavior and ownership are established, with coverage for the selected approach.
