When writing #59658, I found it neccesary to check for warnings in a run-pass test because deny(warning) would observably change the warning pattern I was testing for in the first place.

It would be nice if run-pass would check for WARN, NOTE, HELP, etc. and cause a test failure if those are not found when expected. A bonus point for failing for unexpected WARNs etc. as well.

Is this still relevant?

Probably not, but someone needs to check that there's no gratuitous differences between // run-pass UI tests and other UI tests with regards to WARN, NOTE and HELP annotation.
