Repro Code

declareconsttest:unknown;(async()=>{awaittest})();

ESLint Config

module.exports={parser:"@typescript-eslint/parser",rules:{"@typescript-eslint/await-thenable":"error"},};

tsconfig

{}

Expected Result

There's no guarantee that anunknown-typed value is a Thenable. I'd expect the rule to report a complaint in this case.

Actual Result

No complaint.

Additional Info

await-thenable was first implemented in#192 back in 2019. TypeScript had previously releasedunknown inTypeScript 3.0 less than a year earlier.

Not detectingunknown was noted by@Tjstretchalot in#8094 (comment).
