• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.
• I have read the FAQ and my problem is not listed.

Repro

Playground

{
  "rules": {
    "@typescript-eslint/explicit-module-boundary-types": "error"
  }
}

export function foo(a: string): string;
export function foo(a: number): number;
export function foo(a: unknown) {
  return a;
}

Expected Result

I'd like a new option that makes this code pass, since the implementation signature is not visible to the outside, while the boundary, defined by the overload signatures, is well-typed.

Actual Result

This errors, even with all the allow* options turned on.
