Repro Code

exportnamespaceFoo{// reported correctly?typeBar=1;export{};}declare module'bar'{// should be reported?typeBar=1;export{};}// should be reported?typeBar=1;export{};

ESLint Config

module.exports={parser:"@typescript-eslint/parser",rules:{"@typescript-eslint/no-unused-vars":"error",},};

tsconfig

{"compilerOptions": {"strictNullChecks":true  }}

Expected Result

I expected the rule to report on theBar type as unused, similar to TypeScript's report.

Actual Result

The typeBar isn't marked as unused, though to my understanding it should be.

Additional Info

It seems the issue remains the same if theexport {} is replaced withexport default ..., orexport * from '...'.

I think this is similar to#2867, and I've wrote some of my thoughts about it in#10714.
