I'm unsure about this change. I agree that it makes the error much cleaner, but without the help: ... message how would someone know that they can automatically have the problem fixed?

(as a slight aside, I think we should try use try cc groups like @rust-lang/wg-diagnostics when landing PRs like this or the one that introduced tool_only_span_suggestion - I had no idea this existed and it'd have been nice to follow along with it)

tool_only_span_diagnostics was landed over the all hands because it was needed for a different change, so it's pretty recent.

Tools still will see the same json output, so vscode and rustfix would still be able to apply these. I guess I hadn't thought of the use case of someone running rustfix after running rustc iteratively. Should we mark these some other way? Cyan asterisk next to the error or something?

My only concern is that users who know when they see help: ... that it is something that can be automatically applied won't know that for this error.

Something like a cyan asterisk would be ideal to draw attention to that (it might even raise awareness of rustfix being able to fix these things if everyone's error messages had a cyan asterisk suddenly appear). I wouldn't block this PR on that, so I'll r+ this and we can file a follow-up.

Filed #59103.

@davidtwco added a small tweak to fix some less than stellar spans and marked the other duplicate import suggestion as tool only.
