If the bar is so low that inferior clinicians can pass, that's not a win for AI, that's a horrifying problem with the bar.

Inferior doesn't mean failing, it means below average. You can't get rid of below average by definition.

Entire institutions exist specifically to get rid of below average by test-based gatekeeping. You do not want your doctor or lawyer to be "below average" (worse than most people) in their jobs. Inferior test results mean exactly that, failing the test.
